Huckel's Rule: aromatic vs. antiaromatic (5)

[hockeymo]

QUESTION: If you have a positive charge on a carbon (like the one at the end of the video) is it always sp2? I learned this awhile ago and I forget! thanks

[lagoskid]

@hockeymo Carbocations are sp2

[Thehamez]

As I always like to say, the smartest people are not the ones who know the most. They are the ones who can convey difficult topics in an understandable way.

[GCOOL75]

I wish my Orgo. chem... professor is good as this guy. lol

[kokocipher]

I can't believe my teacher made us memorize so many useless definitions for things =\.

[hitoshubashisan]

you are soooo much better than my pharmaceutical organic chemistry lecturer :)

[mrhansenable]

9:50 every atom is sp2 hybridized. Why is the positively charged Carbon SP2? It doesn't have lone pairs. As far as we can tell it is attached to two hydrogens isn't it?

[Mrinfinite79]

@mrhansenable I agree, I was confused at this part too. Wouldn't it have to be a negatively charged carbon to not a positively charge one?

[jlduong10]

@mrhansenable if it had two hydrogens then it'd have no charge on it. it's (from my knowledge) lacking an atom attachment, meaning the carbon is positively charged and sp2

[MsNatalieRose1]

@mrhansenable Although it doesn't have any lone pairs it is only attached to three atoms (two carbons and one hydrogen), which means there are three atomic orbitals (s, p, p), which is why it is sp2 hybridized.

OMG YOU ARE AMAZING!!!!!!!

[mekbarbie]

i lalalala love YOU !

[thunderstruck619]

Come teach at UCSD! love you man!

[knotnyce]

when you said we are finally ready to start the real stuff a was like YAAY!!!! lol cudnt help it..

[alefonse]

Excellent!! But I have a question , why is the first carbon in the las compound sp2???

[JayyKehh]

i would absolutely pay attention to lecture if this man was teaching....

[TheAnmolKhanna]

how come carbocation is sp2 - it doesnt have a LP so exception should not apply?

[socbe7]

@TheAnmolKhanna It has two carbons and a hydrogen attached to it, therefore it's sp2. This doesn't involve the exception.

[dabigboppa]

Hey bro, can you take my exam for me tomorrow? lol, jk, great work. These are really informative, clear, and helpful. Thanks so much

[arbimoradian]

thank you

you R so through and through

tnx again

[mtksbctk]

oh lol that mariah carey's song is actually on my side bar

[emberleigha]

You should win some kind of medal for these videos. You've awesome!

[IMBLUESTREAK23]

Please come to the University of Kentucky and teach Organic. The goofs here are too worried about academic research rather than teaching chemistry.

[bodmondude]

Sir, you are amazing. 

[cobragirl15]

Come teach at UT Knoxville. Those O-chem teachers are brilliant but simply cannot communicate their knowledge!

Thank you so much

[kapoorankit98]

The best part of ur teaching is,

COMPLETION

thnx alot!!

keep up the COMPLETE work!!!!!!

[iknow66615]

the only god for us -india

[vanheusen0814]

You are the bestttttt!!!! =) Thank you so very much =)

[jtran000]

woot! can you teach gchem!

[malaikaswm]

Thank you for your continued invaluable work!!!

[MsGrammarnazi]

I agree!

Well, I have been trying to get the guy to go out with me! I am in love with him.

One day...he is going to write me! I wonder if I should send him a pic?! :)

[daveyman19]

Your my hero

[jmnc05]

You're videos are amazing!!!! Thank you so much for taking the time to make these, great job!

[nmctelos]

Thank you for your clarity and step-by-step explanations.  Not only should you tutor students, but you should tutor professors in teaching clearly.

[therealLucianWolf]

why do americans insist on saying things wrong!

Cyclic pronounced SICK LICK

sounds like something gary glitter would do.

at least he didnt say alumin UM

when the Iupac spelling the rest of the world agrees on is

aluminIUM

[sufianmahmood]

thnx a lot man!plz also give some lecture on the core concepts of polymer

[lable87]

i like the new definition! :)

[anamcutie]

thanx alot!! you are really a great help!!

[PrinceVen]

wow, thank you so much for doing this! You are very clear and explain everything so well...awesome!

[snakeinapple]

you are amazing! A brilliant man!!
