Orbital hybridization. Sigma and pi bonds (1)

[Denisova321]

Ahhhh, i all makes sense now!

[JapanAzn]

Thank you so much, you explained what my professor TRIED to explain for 2 classes in a few videos.

[Dyenutsa]

How come 95% of all teachers/professors we meet in our school years present their material in a language that only they understand and try to act smart when it could all just be as simple as explaining it as it really is ? i know where my donations will be going from now on... thank you so much for what you do!

[LoXatoR94]

Who else has a test/exam tomorrow?

[121Boohbah]

@LoXatoR94 Ap chem fml -____-

[ZuluTigers]

I have a big test tomorrow on hybridization in my Honor's Chemistry class. You are a life saver man!

[zueshades11]

easy way to memorize electronic configuration ...

"s"chool "s"chool "p"ublic "s"chool "p"ublic "s"chool "d"istrict "p"ublic "s"chool "d"istrict "p"ublic "s"chool "f"ederal "d"istrict "p"ublic "s"chool .. kinda confusing when i wrote it here though :P

[zueshades11]

woooaaahhhhh !!!! this is a little high stuff for me .. im in first year of my college :P i just have one chapter for organic chemistry this year

[sd292817]

she sounds hott

[xxmariaabxx1]

who are you actually teaching? is it a normal school class or home schooling or private tutoring???

[ghattan117]

Helpful, but it seems like you'd rather have it be memorized than fully understood(with the px,py,pz etc* orbitals)

[weiner7000]

very good

[sweetgirlsm6]

you are a grade saver/life saver!!!! Entire semester of orgo with my stupid professor taught me nothings and a few hours before the finals watching your videos made a difference! :)

[smithredhawk]

and just like that I finally understand hybridization

[PartiallyRibena]

I thought a triple bond had delta-bonding?

[fieryblast37]

this guy is the best! nothing of this i could understand from both my school and one other guy i asked to explain. he is just too good

[RadioAlice1]

yeah I probably owe this guy some bucks. remind me when i get into medical school.

[MyAkash95]

please erase the boards properly

[brooks2788]

6 hours of studying , no understanding, 10 min video, wtf , it all makes sense

[chaliezarde]

Oh my god, I have been struggling so badly over hybridization---my teacher just didn't explain it in enough detail, and the book's wording was far too confusing; when it came to apply the problems, I just couldn't. I kept getting the bond orders wrong, and subsequently failing a quiz.

BUT THIS GUY. IS AMAZING. I really feel like I can ace this test (Friday!), thanks to his help! I'll definitely be going over all his videos that relate to the exam and watching them. Thank you so much!

[knotnyce]

you make goin classes seem obsolete :D

[Chilenopart]

This guy is my new hero. He is the reason I am understanding orgo (and I mean 95% the reason bc my teacher is AWFUL). This is simply amazing, so clear. And it's free... I'm def leaving a donation, I can't believe how much of a difference this guy has made in my college career.

[Chilenopart]

This guy is honestly my new hero. Because of him (and I mean 95% because my orgo teacher is awful) I am understanding the material. And it's free... I'm def making donations, this is simply wonderful.

[RahmaaDk]

u are brilliant!!!!!!!!!!!!!

[Fentonjr]

great video. hope you got ass in college for doing sorority girls homework.

[ziggadyboom]

to the 5 ppl who disliked this video...just change ur major..it just wasn't meant to be

[fishyjason]

he looks like allen from two and a half men haha.. but hes good

[healthfreak18]

Thank You. Thank You. Thank You!

[buzzybee186]

In 10 minutes and 9 seconds this man explained more to me than my professor has in 10 hours of lecture, and I am not kidding. What a lifesaver! So few teachers really seem like they want to teach students, to help them learn. Most just have a "method" and go with their method. This guy is genius! Test in 11 hours and now I have a have a decent shot of passing!

[sweetdamage1]

I think I might just pass my exam now.

[kazikazikazikazikazi]

This guy should get a nobel prize for revolutionizing science education!



[skinnirific]

You sir, have saved my life :D

[iansquared3]

this girl sounds like she doesn't need a tutor!

[a20e09c]

you are my hero. heartfelt thanks.

[LesleyCordero]

I'm studying for chemistry SAT and this guy explains it sooo well! I spent forever trying to understand it from Barron's SAT chemistry book and i couldn't understand it; I watched this; and within second I understood it... Such an easy concept now that I saw this!

[Mufflerb]

One of the best things about your method that a lot of books and teachers fail to do is give your students LOTS of examples, examples are the best way for students to practice practice practice, even if it gets redundant it still is best to have these concepts burned in our brains rather than leave us guessing on Test Day. Thank you!

[Venie1986]

i just wanted to say, that i passed my first chem exam (on a university level) - not with flying colours, but i got 14 out of 24, so i didn't do too bad....especially since i find the subject quite challenging. So thanks heaps for letting ur vids to be free!!! Cause they helped me quite a bit.

[mrtsunny]

thank you so much! I was stuck on this one problem for the longest time until now!

[conmister45]

Thank you SO much!

[PoppinCheese]

too bad i didnt see your videos before... my exam is in 6 h and i gotta sleep - > i'm screwed for this one, but at least i can prepare for the next one using those vids :)

[Venie1986]

Mr who ever you are. Come and lecture at QUT brisbane in Australia. We are in desperate need of a uni lecturer who is able to do what a lecturer is supposed to do! Teach! Your videos are so good, i've learnt all what i should've learnt in the 2x2hour lectures each week. Maybe i should just watch the videos!!!! Again, Mr who-ever-you-are, THANK YOU! You have saved me lots of stress :) Thumbs up!

[BreeeeeAnnnnnaa]

@Venie1986 Totally agree!!!

[Igglesnoop]

But it has 4 attached atoms...

[CertainAspect]

Thank you very much for such clear explanations. Excellent videos!

[JRB3000]

Your amazing. But it think you need to be a little more scientific and less simple....

[lolimso18]

So good! it's like.. pie for my tired, tired chemistry brain. My teacher grinds me down with examples and numbers.. You give my brain lovely easy to digest pie =]

[eizhowa]

Worst chapter in my Chem book.

[Soccerjunky04]

This guy is great, what my instructor couldn't make me understand for 3 weeks this guy made clear in 5 minutes. Thanks.

[sowyer22]

@Soccerjunky04 hhhhhh same here man !

[NKindianhobo]

You blow my mind!!! You're absolutely amazing!!

[tootyrc]

wow such a simple concept of hybridization after so many years of chemistry and two semesters of organic i finally NOW get this, like REALLY get it not just know the memorized reasons!...none of my textbooks or professors ever gave me the simplified explanation of hybridization as you did. Thank you SOO MUCH! you are awesome..you have my donation:)

[conorbob0]

I like the bit where he teaches me things.

[dung9393x]

he is genius

[ektaara]

I love you !! you should teach organic in every university !! this is the first time I ever understand this stuff

[Goodfellow7]

Hey I have a question for 3:04, he says the carbon atom with a formal charge of -1 is sp3 (3 attached atoms + 1 lone pair)...

However, carbon has 4 valence electrons, if it has 3 bonded atoms, it only has 1 electron left that is un-bonded, which is not a lone pair, giving it a hybridisation of sp2 (3 + 0 = 3)

Can someone explain why this particular carbon is shown to have an extra electron and thus a lone pair?

[Goodfellow7]

@Goodfellow7 Nevermind I worked it out,

The negative charge of the carbon is due to the extra electron which creates the lone pair in the first place. Brain fart.

[flcl49]

@Goodfellow7 are you familiar with "methyl anion"? it's CH3^-

so if i were to draw its lewis structure it will look likie this **

H - C -H | H

the electron came from else where and sort of "attack" the carbon i guess; so in the end this molecule is a tetrahedral sp3 hybridized with a closed shell :D

[Radgo16]

It's a great lesson but I wish you had mentioned WHY you can have only one sigma bond and the rest have to be pi, and why must lone pairs hybridize?

[sufjanfan92]

this video just saved my academic career

[musicsbff]

thanks..my teacher decided to teach us this even tho it wasnt in the text book.

[xXxTokyoVKxXx]

I'm in 10th grade trying to learn this.. FML.. T___T ...the freakin pi, sigma is not even mentioned in my book, and my teacher expects me to learn this..

[krmlghn]

He's that dude from 2 and a half men!!!!!!

[VeroniqueEmbrace]

@krmlghn haha yea..he does kinda look like him

[dragonfire9267]

i hate you hybridization

please go die in a hole

[bigfatcookie1337]

Dude this shit blew my mind, thanks for the help i appreciate it!

[ivnb92]

8:33-8:41 long awkward pause hahhaha

great teacher

[smartalec1991]

Thnx so much! I finally know how to do the hybridization of orbitals.

[geeiwonder]

thank you so much professor. you saved my life. but i got one question... I was taught that a sigma bond always forms on the axis of the bonding Nuclei, where as the Pi bonds are above and below this axis. so in the case of triple bonds... wouldn't it be imperative to label the center bond as sigma and the remain top/bottom bonds as pi? or i have been misinformed?

[captaindan1892]

thanks a lot! This really helped me and my friend out for our chem mid term in college!

[shadowsaber3]

Can i ask something? What grade studies these things? 

[vheeyel]

i am only a senior student in high school but we are studying these already.. it's meant for college students. i hate o-chem.. but because of this guy.. now.. I LOVE IT. LOL.

[KatanaMasta88]

HAHAHAHAHAHAHAHAA MY TEACHER DROPS THE ERASER ALL THE TIME HAHAHAHAHAHAHAHAHAHAAAA!!!!!!!­!!!

[analemma2345]

What was the exception to the rule that you mentioned?

[Radgo16]

@analemma2345 I would love to know that myself :)

[Caram3lLov33]

thank you

[thoumaturgica]

I like this guy. (Had a German American roomate named Schmidt who looked just like this guy.) 

[pjihae]

Thank you for putting these up!!!

[FMCatherineFM]

life saver for university ><

[Loven1977]

You are an awesome teacher thank you so much!!!

[AndrewThomasR]

im sorry mr hawking, imma let you finish, but this guy is the greatest teacher of all time. OF ALL TIME!

[BernardTunes]

4:31 Duster fail :D

[akame15]

Thank you so much!

[momocowkittylovely]

I dont get it ! =_= that girl knows everything why she even in the video? lone pairs r hunting me (@_@)

[5times12]

love it

[superman0100]

great video. much more clear than my organic teacher explained it, and he took an hour to do it

[BananaPuddin]

@superman0100

Same here. And even after they explained it, it still doesn't make sense. But this guy teaches it very well.

[zackatpak101]

Amazingggggggggg !!!!!

[iamblackmo]

This is great, thank you for making these available

[kiwikid1987]

lifesaver, the day before my organic chem test!
