sigma and pi bonds

[MaplerA]

Looking at the IB chemistry booklet, i had no idea what was happening. First minute of your video. i got it...

[Snuppykira]

is not bad, the unic problem is that I´m not english!! haha and is quite difficult for me to understand... anyway thanks you! ;D

[7035685457]

omfg you are amazing!!

[faz10420]

You are literally the best person in the world. Please move to Guernsey and be my teacher, or my mum - whichever's easiest with you.

[Fob616]

I <3 you

[RethseEcinue12]

Thank you very much. I wish youtube is my teacher. :))

[Dectheboner]

Humans must have more elements in their bodies than any other known substance

[RTSnRPGfreak]

thank a lot for this, i understand more abt pi n sigma bond, bt i forgt wth is sp hybridization, i remember my teacher taught me...FUCK myself

[aish8142]

mam can u plz explain me that when we have a given molecule ..or like CH3 double bond CH2 ..or something...then how do we know that which one is which hybridised just by looking at it?

[groundshaker100]

At 3:40 the hydrogen dissociated from the molecule

[creativsis]

Thank you! Not only was in informational, I actually understand it!!

I wasn't paying attention in class the day the teacher taught this (nor would I have understood, if I tried). >.<

[Oreochocolatedip]

OMG THANKYOUUUUU!!! I have chem exam tomorrow and this definitely helps! :D Thanks so so much, you are much more clearer than my textbook and my teacher combined!

[lilacnyss]

THIS REALLY COMES IN HANDY!

[michaelchukwu22]

people like this make chemistry alot more interesting and fun. thank you

[Spideramun]

the white hydrogen is being being a bitch ... keeps rolling around ...

[teapot12999]

Thank-you sweetheart. You've cleared my troubles about this topic completely. <3

[psunsrox]

thanks the visual was very helpful in helping me understand

[Dropstats]

tyyyyyyyyyyyyyyyyyyyyyyyyyyyyy­yyyyyyyyyyyyyyyyyyyyyyyyyyyyyy­yyyyy

[Guiguiggs]

Thank you!

[ttoosh]

chem monday fml

[justger]

Words can not explain how much you have helped me... I love you.

[virginialikesyou]

Thank you I just reviewed an entire chapter in 5:02 minutes!!! Thank you thank you thank you!!!

[hampsternips]

sooooo helpfull, where was the camera places :P

[csugesad]

Lmfao @ the beads dropping off from the dough diagram

[Ahkmedz3bola]

Thanks alot! XD I had this annoying gap not knowing sigma and pi as we went deeper and deeper in chemistry LIFE SAVER!

[sohoyankee66]

Things make a lot better senese to me after watching your video. Thank you for posting it. And no I didn't notice your electron jumping off your molecule and rolling away. :)

[sohoyankee66]

Things make a lot better senese to me after watching your video. Thank you for posting it. 

[KyuhyunDonghae]

you just saved my life =] i never learned pi and sigma bonds in my ap chem class and my ap exam is coming up so this really helped me =D

[bishounenlover17]

Thanks! :D

[dodokhan1]

This was awesome.....! Thank you...! U ARE 100 TIMES BETTER THAN OUR CHEMSTRY TEACHER.

[flare765]

MARRY ME!

[gule41018]

thank u very much. i really learn alot from this vide. you should have youtube channel like KHANACADEMY just for chemisty

[FlameDesire]

great video!

[MonaRocks09]

I LOVE YOU SO MUCH I HOPE YOU GET EVERYTHING YOU WANT OUT OF LIFE THIS HELPED ME SO MUCH OMG I WANT TO SEND YOU A HUGE FRUIT BASKET

[aom9010]

you explained this very well.thank you so much.

[jazzangelreloaded]

I'm actually following the tip of your pen with my mouse as you explain things - thanks so much for posting these videos (esp thanks for all the effort)!

[Mizabella01]

it's a great video but i still don't get it. maybe i should watch again. ^^

[TheAlicat92]

Thanks! This helped alot!

[yourfansterrr]

From the 3 sigma bonds and 1 pi bond, how did you get sp2?

[deadxfamous]

Hey thanks for making this video! i found it extremely helpful.

[Syedaxox]

THANK YOU!!!

[kidarrowz]

i cant express my gratitude right now

[ws1090]

I have an hour and 45 minute organic class. Somehow I got more out of this 5 minute video than the whole lecture. Thank you for explaining the basics in an easy way. You are awesome.

[flodhi1]

I want you to have my babies!

[kganzert25]

Why cant my professor explain things like this?? She covered everything in 5 f_ing minutes...AWESOME!!!!!!!!!!

[natixoch414]

Thank you so much

[purplepick1]

you are very very good at explaining. Also the voice is so clear. How did you record it with such high quality?!

[debbiesna]

hmm i have a doubt...why is a double bond a sigma bond and a pi bond?

[debbiesna]

:) That makes sense to me. Thank you for making chemistry easier.

[maddles0301]

if only my chemistry teacher could teach me this. thank you!

[88res]

I wish you were my teacher

[SilentKnight719]

also, WHY DOES THIS MAKE SO MUCH SENSE

I DON'T UNDERSTAND MY UNDERSTANDING OF CHEMISTRY NOW

[SilentKnight719]

4:10 she broke the atoms and caused a nuclear explosion

[spaedy4ever]

That was extremely helpful, thank you

[jacoppedge]

I wish there was U.N.I bond because i seriously love you now.

[Syedaxox]

@jacoppedge lol xD

[ImUberAsianMan]

I get it now.... thanks a million!

[Kaitano94]

Has anyone noticed that chemistry teachers suck compared to the people on youtube?

[MissV247]

@Kaitano94 I totally agree. Here, they really want students to learn. At school they just want students to repeat in these subjects so they can make more money.

[dwtimmons]

@Kaitano94 Its all about job justifibility! Complicate the subject so they can justify their 20 years in college to teach.... and do nothing else productive towards society... I love teachers... don't get me wrong.. but seriously... why do teachers have to over-complicate subjects and give tests designed to fail students???

[rockinngabhishek1]

@Kaitano94 u r damn right bro :)

[iluvyouwyatt]

@Kaitano94

Nah my professor is actually pretty helpful. Nothing wrong with getting a different perspective on things though.

[XtRedChaos]

OMG... i get it now. :D

[Arrow2brain]

wouldn't the bond angle on C2H4 between central carbon and hydrogen be more than 120 because of that double bond?

[billandben0000]

this is fantastic, it's clear and very easy to understand, thank you so much!!

[10mrlegend]

this lesson ruining my life , by the way the teacher show our class this video , thnx i'm so happy to find this video :)

[SwannGrl713]

You saved my life!!!! Thank you :)

[abhischool]

AWESOME

[Mootsterdotcom]

Hey I think I know you, is your name parker by chance?

[wllywaliy]

you are the chemistry god! I needed your videos last year to help me with lewis structures, now you have helped me with sigma/pi bonds. THANK YOU!!!

[davie4monster]

( 3 ) ..Ladies and Gentle-men, I have just explained the difference between "male" and "female" conceptual abilities in a way only a "bie=sexual person" could conceive of.

DavieMonster

[davie4monster]

( 2 ) The "region" of highest probability is actually a space around those lines, isn't it.?? NOT the area Enclosed by those lines,, Right..??? ..The electron is NOT really likely to be extremely CLose to the nucleus, is it..???

And now i've gone beyond your conceptual ability, lost you, so we'll go back to your Simpler concepts, build a house of "Steps which you ReMember," pass the course, and Do Well...!!! :)

[davie4monster]

No, this is Not true, these shapes define the most likely place you will find the electron, considering ANY WHERE IN THE UNIVERSE. Yes, the electron could be anywhere in the univers, NOT just "in that space." Thus, your visual grasp of the basics of "the statistical reality involved" is formed in only a "baby" kind of way.

[Feanic]

The hybridization of an atom can also be determined with the Steric Number (SN), where SN 2, 3, 4 are sp, sp2, sp3 hybridized.

[daltimplay]

Thanks a loooooooooooot for your video!! I wish I could have been introduced to molecular orbital theory in a similar way but I wasn't. And that's why now I have to waste my time to look for better explanations about the theory on youtube. Thankfully, there are people like you to share such a great video. Cheers!

[heyshutupyou]

chemistry at NC State is hard. this helped. so i love you too.

[AvidLearner11]

I appreciate that you're not a badly dressed guy standing in front of a whiteboard insisting us all to understand from drawings. Thanks for the clay model--it was crucial to my understanding.

[lifeDotGov]

what the fuck?

[Gloubolz]

Thank you very much !!! Tu me sauves la vie.

[luckyrockeragmyt]

shouldn't pi be stronger, as they occupy more area?

[pandixon]

@luckyrockeragmyt

Sigma bonds are stronger because the electrons in the overlap are attracted to their own nuclei and the adjacent nuclei. In the pi bonds, the overlap regions are not between the nuclei. Ruchieru has a good explanation for that.

[Angipiche]

Very tough

[mrbigbiggestfan]

thanks berat gan

[muzh931]

isthis your own video.if it is you have done a great job.really helpful

[ninjajesus81]

You sound like Jodie Foster in Contact.

[tusharpatil81]

good contest for 5 to 12 kids on attanolearn com and win iPad

[gooddariuz]

hey shouldnt there be 1 sigma but 2 pi bonds for C2H2? I'm kinda confused haha :/

[sweetbabeey]

good lesson!

[DonChedda]

Thanx, recap for my exam tomorrow...xO Wish me luck.

[Toaderson109]

Thank you SO MUCH!!! You rock!

[MrBrianbeyer]

This is some good shit.

[SSJkiller]

@ 3:12: Wouldn't the double bond repel the single bonds further, making the bond angles a little more narrow between the hydrogens and a little wider between the hydrogens and carbons? Maybe I'm confusing double bonds with free electron pairs, but I'm just wondering.

[stardanny33]

@SSJkiller

You're right, the pi bond does repel a bit making the C to H angle ~122 and H to H about 117. But she was just giving the general approximation. But good application of the repulsion theory.

[SSJkiller]

@stardanny33

Thanks :)

I'm getting my BA in Biochemistry right now and I'm about to enter my 2nd year. Wish me luck in Ochem =/

[stardanny33]

@SSJkiller

Cool, I'm about to finish my Biochem major (1 more year).

And orgo is cool...not as bad as everyone makes it out to be, especially the first semester.

Check out this site, it's pretty amazing..

Google Dr. Jasperse Mn state chem 350...has really great notes and practice material for orgo

good luck

good luck

[janitarjanitar]

I love how the hydrogen rolls back on the scene at 3:42 perfectly in sync with you saying 'overlap'

[IronMaiden43ver]

Is this a material for 9th grade in a 12 grade system? I'm realy curious cuz it's in our 9th grade books

[chettync85]

i love her more johnfinfin.... in 5 min i learned WAY more than I have all semester.

[antonyfl]

Great videos! Lots of help for my first year chem!

But your video editing is scary, for some reason it reminds me of a horror movie because sudden jumps between scenes :P but very good thank you

[dimseeeen]

thx

[ganistio]

thankss a lott!!

[haroonbaig56]

Thaaaaaaaaaaaaaaaaaaanks Aloooooooooooooooooooooooooooo­ooot.

[barak219]

if i am asked in a question what is the orbital overlap of the Pi bond in NO3-, can it be anything but p-p?

[stardanny33]

@barak219

all pi bonds in resulting from elements in the 2nd period (C, N, O) must use their 2p orbitals to overlap sideways.

going down the group, it gets complex.

To answer your question, only p - p overlap exists in nitrate

[scrad245]

Thank you! Revising for my IB exams and this has really helped!

Just covering the entire syllabus again and making sure I've got everything, and this made things a lot clearer!

[R4zr93]

Thanks sooo much. My teacher sucks and gives us homework without even explaining it. I got a 100 because of you!

[godspeed28]

Dude, I fucking love you!

[scothu]

finally... i understand!

[strwbrrygyrl16]

this was a HUGE help!!! most chem teachers just fly through it but this explained it perfectly!!!

[thee1spleffy]

Doing last minute for my Advanced Chemistry revision 2 moz, really helpful thanx lol

[Clementmashinini]

This a great elaboration. It has helped me alot

[italianloveforever89]

thanksss, u helped a lot.

one question: if we have this molecule NCCHCHCH3, how many sigma bonds do we have ?

[uakhiltube]

EAsy to understand.need more things from organic chemistry....isomerism,,qualit­ative analysis and all

[nilrama1]

thank you very much,, you are awesome,,,

[pianopan8]

so helpful! thanks!

[lotoo2]

Well Done.

[bleachedbutterfly]

i love you

[csantos222]

Thank you very much.

@ 3:55, if there are four total yellow sections, representing the four ends of the p "dumbell" then only two sections are creating a bond? So the double bond comes from the s orbital and then one of the p orbitals?

[redsoxmtexas]

first sigma bond=(.)(.) boobies!

[FunkkkShawn]

I didn't really understand the clay part, but thanks! Really straightforward.

[sebbybob]

made more sense than my prof :)

thanks.

[DotDotDotDotDot]

Thank you so much! That makes so much sense now!

[ashgurl22]

Thank you! I told all my friends who are struggling with this concept as well.

[dbanner126]

*Playdough FAIL haha

Good video thought!!

[bestlessonslearned]

Thank you for explaining this so clearly! I was able to complete my homework! : )

[minhmeo1209]

man

I kinda dun get it though

Watch again

[CocoMilkCheese]

OMG i am soooo grateful! u explained it so well! thanks!

[naomitjuh91]

This was really helpfull, thank you! Great overview and explanation.

[johnfinfin]

I love you.

[Enelya00]

VERY helpful :)

Thanks!!!

[latulipanverde]

You are awesome!! Thanks for taking the time to do this video!!

[g0rbehsigari]

why the pie bond is weaker than sigma bond?

[ruchieru]

pi bond is composed of overlap between two parallel p orbitals, there is less of an overlap between these two p orbitals due to their parallel orientation, as opposed to a sigma bond, where the overlapping happens along the internuclear axis.

[MsHilary100]

because the bond overlap doesn't occur directly between the two nuclei.

[Radeon]

you rock

[AEAE9373]

great video

[HelloMangoJlo]

this made it so simple! thank you

[BHQuicksilver]

very helpful. I wish you were my organic chem teacher

[TamilEelamTigers2009]

wonderfull

[surbhidhuppi]

great video. helped a lottttt!!!!!!!!!!

[KiraraHonya]

Gracias!

[leoshil]

thanks a lot. u rock !!!!

[27ruby]

i have a final tmr!! thank you SOOOOO MUCH!!!

[0opassionateOneo0]

your wonderfull!!!!!!!!!!!!!!

[mhmalik25]

ok maybe i dont get this video because i dont get how orbials form nodes. those loby thingies.

[futhark3]

Your videos are great! Thank you so much!

[NotPotable]

I love you.

[flyingm3x1can]

this is wonderful

[sammen89]

What would the answer to this be? The molecule H2C=CH2 uses what type of hybrid orbitals for the sigma bond between the two carbons?

(the "2" is subscript)

[CarnalDiafragma]

Two sp2 orbitals make up the sigma bond there

[fAM199]

Thank you very much for uploading this type of a video......

This helped me a lot in my advanced studies.

I was wondering what this Zigma and Pi bonds were.

Thank you once again and hope you will help us in the future also

[onealr]

Thank you video is very helpful 5*

[kidwhocracked]

Another thank you. This was helpful.

[Darkuyt]

thanks, i could not understand the types of hybridization without this video

[loosseeyy]

Thankyou, this has helped alot :)

I now kinda understand it! haha

[padsblack]

i actually followed this, thank you so much. now i just have to figure out how to write them for my assignment lol

[judyshin1220]

sooo good, i am taking a correspondence course and you do not even understand how much this has helped. i watched other people on youtube, this has probably been the most visually stimulating, educational, understandable, and entertaining to watch. thanks.

[Ractalfeces]

I see what you did there...

[achester27]

this makes so much more sense, thanks for uploading this!

[jammy41]

fabulous....truly fabulous

[dania7986]

it's both.... you first hit this in gen chem and it comes back in organic. need to really understand this throughout.... from high school onto college.

[Eily000]

thank you....I could finally understand this thanks to you.

[eldominicanboy]

is this AP chemistry? I'm taking an introductory chem class right now (I'm in 10th grade), and my teacher has not taught us this stuff

[johnnyd101]

sound

[JustJakeat132Bpm]

That was super helpful. Thx a ton.

[xEternalx]

Can you explain why a double bond is a pi and sigma bond ? It wasn't mentioned.

[jhoa001]

any type of bonding always has a sigma bond. sp, sp2 , sp3. they all have an s which represents a sigma.

[xEternalx]

hey Jhoa001, can you tell me why?

[jhoa001]

you always need to start with the lowest energy level. You can think of sigma as the lowest energy level. s- orbitals look like spheres and p orbitals are dumbell shaped. so when u put two spheres together there is overlap in the same plane. When u put two dumbbells together in a pi bond. there is overlap both above and below the plane. this is where the second bond comes in.

[xEternalx]

oh i c thanks.

[TTUchem1010]

In a double bond:

1) The sp2 hybridized orbitals (green) overlap to form a sigma bond. (The electron overlap is between the nuclei).

2) The two p orbitals (yellow) overlap to form a pi bond. (The electron overlap is above and below the nuclei).

[xEternalx]

LOL. you were like "Where are the overlaps" then you said "Look they're here. They're 'shaded'"that last emphasis on the worded shaded didn't imply that we're dumb if we couldn't see it right?

[Wampa181st]

nice, very helpfull

[PyroTechy90]

Thanks for clarifying sigma and pi bonds for me =)

[armanipure1]

Your clips are very helpful! Thank you.

[sterling729]

thanx!

[nkhannm]

thank u buddy.... very much.

[sasmadrid]

thanks thanks, very useful and easy to follow :)
