  • i loooove this teacher!! she helped me out everytime!! who cares if she talks fast as long as you keep attention unlike all these boooring slow taling teavhers

  • SLOW DOWN YOUR SPEECH!

  • @4:49 lol

  • You are a lifesaver :D

  • thankyou very much you r awesome

  • NO I LIKE HER GOING FAST>.. lol

    shes getting to the point faster!

  • I think N2 should have sp2 b/c it have a sigma bond and a lone pairs.. can you please explain that?

  • @seifdeiab In N2 molecule infact no hybridisation takes place.In N2 the two N atoms form a triple bond i.e. one sigma and two pi bonds whereas hybridised orbitals can only make sigma bonds.All of these bonds are formed simply by the overlapping of three p orbitals of each N atom.Moreover hybridisation takes place only in those molecules which are at least triatomic.

    Hope this helps.

  • Youtube should have the option of slowing down a video.... I am grateful for the help thu ! thanks !

  • chemistry :(( mini quiz 2moro :((

  • Where can i find the lenthy lectures on biology? please comment

  • why does carbon forms hybrid orbitals with 2s and 2p orbitals? Isn't the valence orbitals of carbon supposed to be 3s and 3p orbitals?

  • thz teaching is perfect!

  • If you want slower talking go to khanacademy. This is what makes brightstorm so awesome, they just get straight to the point and teach the material quick for us ADD folks that would otherwise tune out 15 min into the video :)

  • IM TRYING TO LEARN... SPEAK SLOWER

  • @lopa29july Im Chinese and I could understand what she said...

  • At 3:35 I think there should be a correction. A pi bond is not a direct overlap of p-orbitals, but a sideways, parallel overlapping of p-orbitals. Only sigma bonds are direct overlap of orbitals or more specifically a "linear" overlap.

  • My prof seriously needs to just show us your vids in class rather than ramble off notes from the textbook company. I bet everyone wouldn't fail the exams then

  • Thank you

  • Thank you. This helped me feel better about the quiz, but I had to catch back up with you about the multiple bonds and the orbital counting in that

  • Comment removed

  • Slowownndausebetweenyourthinki­ngithelpsusunderstandbetter.

  • I don't get it when u arrive at the end! triple bond, sigma shouldn't be in the middle of pi?

  • @Ameden7777 in a multiple bond (such as triple or double) you just need to worry the one of the bonds is noted as a sigma bond

  • got it! thank you ;)

  • if u guys think she speak too fast, it means ur english listening skills sucks =]

  • outer atoms aren't hybridized i think you just leave them!!!

  • @TheKb135

    definately not, according to quantum rules, if you have different energy levels within the same quantum number then that state is not stable

  • @786mansoor786 wow i've never seen a case like that..like CCl4 the chlorines would never hybridize but the carbon would aha

  • Brilliant

  • thank you so much <3

  • The idiots who say she is talking to fast are just idiots, I was able to follow along perfectly fine. Keep up the good work.

  • You are as cute as you are helpful, and your really helpful ;) ;) ;) Thank you

  • I have watched so many of these videos I have no idea what any of it means I'm so confused :( I feel so stupid but I'm not haha

  • ...Why does she resemble so my old psychiatrist?

  • pause at 4:48 xD

  • totally saved me for chem final! thanks

  • You are a great teacher, you'll never know how much you helped me. Thank you.

  • You are my savior.

  • This was exactly what I needed. Great job explaining it. And since I'm a little ADD (I HATE when teachers go slow) I loved the speed. Then you can pause and repeat if you don't understand something but you don't have to wait if do...

    THANKS!!!

  • Maybe she speaks a little bit too fast... But now, I TOTALLY MASTER THIS!!!

  • she lost me at the end

  • Well ur helping me so much and if you find her talking too fast then go to someone else.Its not that hard

  • Wow, this makes so much sense now. I agree with others that you are talking a bit too fast, due to nervousness. I don't see why though, because you know your material.

  • Comment removed

  • I totally feel her stress. I am not a native english speaker, but I talk as fast as her during the chemistry lesson like firing a machine gun cos there is so much running in your brains. You have to learn how to space out your dialog and make sure your audience understand you with more diagram and examples.

  • I lost you at 5:00, can you slow down please? Otherwise the rest I understand, thanks

  • chill out people she only speaks fast in the beginning

  • It was going great until she got to the multiple bonds part. I'm now confused.

  • oxygen is sp2 because of the two lone pairs?

  • Slow down pleaseeeeee

  • thanks! that was really helpful.

  • This helped alot. I watched your video twice, then re read the section in my book and it made a lot more sense to me. Especially about the multiple bonding. Thank You.

  • isnt the last structure a resonance structure? or am i confusing that with CO2 or something?

  • love the video. straight to the point, no nonsense.

  • You need to explain some WHY WHY WHY's 

  • I understood, but hardly.

    My english is rather good, but I couldn't recognize some words.

    Please,slow down.

    The rest is excellent.

    Greetings

  • confused

  • ... faster talking=faster learning

    lol?

  • I love the info in these videos, but I agree.. so fast it's hard to learn anything

  • My gosshhh could you speak any faster!

  • all this woman's videos are too FAST! i know you want to hurry, but thats the reason for these videos to help people, and going fast isn't helping....

  • I got a little lost once it got to the multiple bonds part.... Does 1 e- go into the p from the s shell in the C 2s?

  • she is really faaaaaaaast ..i feel nervous !!!!

  • that was a great explanation. Thanks!

  • Btw that would be a cross bike

  • Whaaaaaaaaaaaaaaaaaaaat??

  • i feel stupid

  • @lionw8 I hate not knowing info right away but that is why we practice, just stay away from the smug bastards who are in a class, that you have not take, so they don't ask you "OH...You don't know about wave functions yet, I learned that a long time ago." It's why when I help people in class I don't act superior. It's why I HAAAAAAAAATEEeeee 90% of college students, attitude. Because remember there is a difference in how smart you are and how "educated" you are

    .

  • i have a test on this tmr... fml

  • i wish my chem prof was this good

  • She is very lucid and explains things on a level that is intuitively satisfying. Thanks!

  • Im cursing myself for not watching her videos before....very nice...

  • I learned more from this person in 6 minutes than 3 weeks of class.

  • THANK YOUUU!!! :DD

  • I thought you did a really good job, the only problem I had was that you spoke kinda fast, but thank you I get the concept a whole lot better now

  • trollface at 4:48

  • Guys I have a REALLY good solutions. Put your mouse-cursor over the button with two lines in the corner of the video that looks like this ----> II . we know as that as "Pause". Now click on it and you will notice it becomes the symbol for "Play Video".

    Now keep repeating this constantly for about 400 times over the video and thus we now have a manual "Slow Down" feature!

  • slow down .......yeah!

  • Thank you for your help :)

  • Oh... thanks, or else it would be an hour to explain.

  • actually in N with N with a triple bond the midle is sigma and the other two are Pi :/

  • thanks, but.....why so fast? Did you need to go somewhere 0.0?

  • Or..you can determine the number of Hybrid orbitals of each by determining the steric # of each atom. Just simply the number of areas were bonding or electrons are present around the atom. For example..carbon with a Steric # of 2 = sp Hybridization; Steric # of 3 sp2 hybridization; and Steric # of 3 = sp3 hybridization

  • Cut the coffee cup some slack woman!! Nice video though;)

  • slow downnnnn !!!!!!!!!! plzzzzzzzzzzzzzzz

  • SLOOOOOW DOWN! I understand this concept already, so I could (barely) follow along. If I were trying to learn this concept for the first time, however, I would have stopped the video about 10 seconds into it. Sure, I can pause, rewind, etc., but that takes more time and energy than finding a superior video in the first place ... they're just a click away.

  • Awesome!! Lot of info in short period time. I completely understand this now. I'll be looking for more videos from you. As for the folks on here who say she speaks fast..its Youtube! just rewind and play again!

  • Yes you talked fast but its a lot of info to get into one little video. I think you did an amazing job and you saved my chem grade! Thanks!

  • helped me understand the concept better!!!

    thanx! :)

  • whats the rush?please slow down

  • thanks! helped a lot :D

  • You are speaking so fast.

    You did a mistake in NH3, the last electron should be filled in the first orbital in sp3.

  • Guys, she's probably talking so fast cuz she's nervous. I would be O.o

    But this video helped soooo much!!! 

  • @ktmcpherran2341 Sympathetic nervous system take over...

  • at 2:56, why would all four of them be the same? I thought lone pairs are more repulsive so they shouldnt be equal?

  • @Termin8trix Lone pairs aren't really repulsive in this case because, remember, each orbital can have 2 electrons? lone pairs are just 2 electrons in a orbital - meaning in this case at 2:56, one of the sp3 orbitals has lone pairs (2 electrons). Just to extend, there are still 3 more sp3 hybridized orbitals with 1 electrons in each. They aren't happy, cuz they want 2 electrons. And then 3 hydrogens come into play, and provide each sp3 hybridized orbitals with 3 electrons from its s orbital.

  • why do you start with 2s? shudnt be 1s first?

  • @zezo7hdk 1s is too stable already for it to participate in bonding. Just think about how close it's to the nucleus...it has very low energy...it just sleeps in there through its lifespan.

  • why arent the 2p orbitals filled with 2 electrons each? "each orbital is occupied with 2 electrons" that's what my chem book says!

  • @zezo7hdk Not all 2p orbitals are filled with 2 electrons. Remember there are 3 2p orbitals. 2px, 2py, 2pz. If you look at 2nd row, Boron only has 1 electron in one of its 2p orbitals...to arbituarily pick one, i'd say 2px. Carbon has 2 electrons in its p subshell. 1 in 2px and 1 in 2py. Nitron has 3 electrons in its p subshell...1 in 2px, 1 in 2py and 1 in 2pz. O then gets its 2px fileld next. so it would have 2 electrons in 2px, 1 electron in 2py and 1 in 2pz.

  • @zezo7hdk Didn't have room in the previous comment but continuing that method, you will see that for fluorine, there are 2 electrons in 2px, 2 electrons in 2py and 1 electron in 2pz. (hence 7 valence electrons - that is electrons in the outer most orbital). Finally the noble gases has 8 valence electrons...2 in 2px, 2 in 2py and 2 in 2pyz. So AT MAX, 2p subshell's can have 2 electrons but this doesnt mean that all the 2p subshells are filled in all the time. Hope that helps :)

  • @tarunslife thank you so much :)

  • SHE TALKS TO DARN FAST!!!!!!!!!!

  • i think you are a great teacher, one way you can be better is if you just slow down a bit. You're speaking so fast, that you're tongue is having a hard time keeping pace with you brain... you keep stumbling. All in all - you're a great teacher and this video was very helpful. Thank you.

  • u are too fast pls but gud though kiss

  • I tried going back in this one part like 10 times to understand you but still couldn't. This would be so helpful otherwise :(

  • Great explaination but please, slow it down a little. Not all of us are a smart as you.

  • thank you this helped a lot! :)

  • so nice. but you forgot about WATER molecules

    

  • so nice. but you forgot about WATER molecule..........

  • so fast.... wdf..

  • i liked it. i think she reasoned that we could just stop it and go back if we didn't understand something. which we can.

  • i love you. this was fast but i still love you. I GET IT NOW *high fives self* ^_^

  • Can you go a little faster so I can not learn more quickly. sorry.

  • I'm sorry I don't speak Spanish.

  • wtf did just happen ?

  • @flaminco666 lol youre so freaking right (:

  • @flaminco666 LOL

  • Nice.....BUT....PLEASE...SLOW.­.....DOWN!!!!

  • @manthalatrice My professor talks at this speed but with a thick accent...it is totally why I am on youtube right now. XD

  • what i meant to say was....ur beautiful :)

  • you speak too fast. , cant understand.

  • Thanks for your help :)

  • way to fast

  • You go to fast. So confused. Thanks. -.-

  • Lol

  • i bet you can read the bible aloud in 2 minutes 8/

  • You should speak slower when teaching something!!

  • why is there a pi bond ???

  • its nice but you speak so fast!
