17.2 Aromatic vs Antiaromatic vs Nonaromatic | Organic Chemistry

[@Dreamy2121]

I owe my life to you, sir. Great job explaining everything. Thank you so very much

[@ChadsPrep]

You are most welcome.

[@omarhalimi1685]

Okay, let's talk about why your subscription hasn’t hit a million yet-that's crazy! You've saved me so much time and stress. I've been recommending you to everyone I know

[@ChadsPrep]

Thanks for all telling others about the channel!

[@avac3036]

These videos are so useful. My ritual is to take notes following all your videos before starting any homework problems. My final is tomorrow! Thanks for everything Chad, I'll be here when I start Orgo 2.

[@ChadsPrep]

Glad the channel is helping you - hope you do well on your final!

[@denissemedina4619]

Sir you have no idea how much you’ve helped me this semester so far 🙌🏻

[@ChadsPrep]

Glad to hear it, Denisse M. - Happy Studying!

[@prettypottedplant]

best video to exist for pre-meds. currently studying for my OAT and this is a lifesaver, thank you!

[@ChadsPrep]

Glad it was helpful!

[@vaughn5755]

Chad your videos are the best out there on OChem, seriously! This is the last unit for my OChem #1 course and I have been watching your Ochem playlist this whole summer semester. To say your videos are great is an understatement.

[@ChadsPrep]

Glad you like them and Happy Studying!

[@iz532]

Just wanted to let you know that your videos are vital for my ochem studying.

[@ChadsPrep]

Glad you found us, lz - Happy Studying!

[@emmies1426]

Really great video. Explained this concept better than any other video or explanation I have gotten from my professors.

[@ChadsPrep]

Glad to hear it, Emmie S!

[@daisylee3925]

Wow! Best lecture in my life. Thank you very much. I was suffering from reading organic chem book 5days before quiz. I can solve almost most of the problems in the book!

[@ChadsPrep]

Great to hear - hope you do well on your studies!

[@fatimashah7641]

How can the square on 12:49 have 4 pi bonds when it only has 2 double bonds?

[@adamscompkitchen]

Each double bond consists of 2 pi electrons in the p orbital of the carbon, so there are two sets of two in the entire molecule.

[@selda.mustak]

the lone pairs part was very well explained! thanks a lot!!

[@ChadsPrep]

You're welcome!

[@Arm0005]

Thank you! That was explained really well.

[@ChadsPrep]

You're welcome, Mohd Raheem!

[@princeysuryan2561]

Professor, thank you very much for making the playlist, it is really easy to watch the lectures in the series

[@princeysuryan2561]

Prof. I asked you a question , but you did not answer, I think you are a little busy.

[@ChadsPrep]

Glad you like the playlist - yes, always busy.

[@adamjanks4966]

Wow this video is amazing thank you so much! My prof completely skipped over the cation and how the lone pairs work so I was so confused when doing homework. Your video helped a lot.

[@ChadsPrep]

Glad it helped you - Happy Studying!

[@tahsinuddin]

So how do you know if an annulene structure is planar? And how can you automatically tell that it's conjugated? Thanks so much for the video!

[@rynn6796]

Thank you so much! Keep up the great content.

[@ChadsPrep]

Glad you are finding it helpful, Rynn!

[@Czar_Char]

i want to know how you are able to tell so quickly if the structure will be conjugated?

[@yussele]

Thanks man appretiated, a true Chad.

[@ChadsPrep]

You're welcome!

[@chriscorrao1011]

Another Great Video!

[@ChadsPrep]

Thank you!

[@TheArtsyCrafty]

Hi Chad! If there is a carbonyl group present in the ring, how would that affect aromaticity?

[@peybak]

Chad, a while back, I made a comment on one of your videos (maybe resonance) about Nitrogen being tricky in a ring. This is what I was getting at, haha. Thanks for the video.

[@ChadsPrep]

Glad it helped!

[@keatonbrunner3562]

You are so amazing for these insanely helpful videos. However, I am confused as, per my course, the 1H azirine is antiaromatic and not non-aromatic. I am unsure why given it should have the option to stay sp3 and not become antiaromatic? Everywhere I look online states that is is in fact antiaromatic?

[@ChadsPrep]

I would have thought nonaromatic also. Check out *Note 4* at the bottom of the following page. www.masterorganicchemistry.com/2017/03/27/antiaromaticity/ A very informative and comprehensive article. It appears that [1H]-azirene is so unstable that it is never observed. The author's claim here is that the easiest way to explain this instability is that it is antiaromatic. I don't know if it is conclusive, but the author, James Ashenhurst, is brilliant so I'm not going to be quick to doubt him!

[@keatonbrunner3562]

@@ChadsPrep Thank you very much for the reference! So in respect to your thoughts, does this mean that every lone pair on nitrogen then will be a part of the p orbital, ultimately playing into the overall bonding molecular orbitals? Be it for any cyclical, conjugated, planar structure?

[@patriciablazon8102]

this was amazing as are all of your videos. thank you so much

[@ChadsPrep]

You're welcome, patrica - thank you!

[@mohammadrezaeh6504]

You are awesome! please make more videos. Thank you for useful videos.
