its been too many years that i have been studying chemistry but i was never able to understand how did this work, i used to cram it but the way you explained it was phenemenol.now i know it all. thanks to you. may god bless you
I rate you a 100%. I've been spending more time on TH-cam trying to understand resonance but in your video I understood in less than 5 minutes. You're the best
thank you so much, your videos help me heaps to understand the organic chemistry... i always wondered why there is no charge on nitrogen when it is in an nitro, then i found the answer in your video that the no2 is net-neutral because of presence of both positive and negative charges
I'm watching these as I'm going to uni for chem:) these qre amazing. I wish I listened to my ap chem teacher's advice of wqtching these for chem olympiad
So which of these structures is more stable and which one is less? How does the number of possible resonant structures influence the stability? More structures is better?
My goal in this video wasn't to compare the stabilities of these molecules. But yes, the more resonance structures that a compound has, the more stable we consider the molecule to be. For more on resonance, see my series at leah4sci.com/resonance-structures-in-organic-chemistry/
for that final resonance structure of the molecule with NO2, does double bond have to be put back onto the same oxygen? Or could you choose to put the double bond on the other oxygen?
You could choose to put it on the other oxygen! They are equivalent atoms, so either way works. Just make sure you don't double bond them both at the same time because that would violate the octet rule for nitrogen.

It’s not that toluene doesn’t have resonance. It still does in its ring structure. The idea expressed in this video (6:12) is that the methyl substituent on toluene can’t participate in the resonance because it doesn’t have a great source of electrons. It has neither lone pairs nor pi bonds. It also can’t receive electrons because then the octet rule would be violated for carbon.
I’ve drawn out all possible resonance structures for benzene at 5:30 in the video. I don’t quite know what you mean by ‘internal resonance structures’. If you’re speaking of the ones in which there is a separation of charge, they do technically count as resonance structures for benzene, even though they are only minor contributors.

I don’t know which exact example you’re referring to, but the idea is that a pi bond is a source of electrons which are delocalized. These electrons can move around the molecule to form various resonance structures. They can rest on an atom as a lone pair or form new pi bonds in other locations.

Amazing session!!! I just clearly understood this !!!
Glad it was helpful!
you r a very good organic teachr good job :*
Thank you!
Wish I’d found this earlier!

The best lecture of chemistry in my life thanks a lot
Glad you enjoyed it
Thanks ma'am
This video was informative.
I'm glad it helped
Oh thank god there are good teachers in the internet
Thanks! Glad to help!
Believe me i have watched many vedios to understand resonance . But this is the 1st one that I feel I understand properly. ☺️😉
Wonderful! I'm so happy to hear that!
SOOOO GOOD WITH THE COOR CODE!!!super helpful!!
Yay! Thank you!

Is the reason touluen cant participate in resonans because the carbon cant donate nor receive electrons or because it is sp^3?
It’s not that toluene doesn’t have resonance. It still does in its ring structure. The idea expressed in this video (6:12) is that the methyl substituent on toluene can’t participate in the resonance because it doesn’t have a great source of electrons. It has neither lone pairs nor pi bonds. It also can’t receive electrons because then the octet rule would be violated for carbon.

so how many resonance structures does benzene have? should we count the internal resonance structures?
I’ve drawn out all possible resonance structures for benzene at 5:30 in the video. I don’t quite know what you mean by ‘internal resonance structures’. If you’re speaking of the ones in which there is a separation of charge, they do technically count as resonance structures for benzene, even though they are only minor contributors.

Your video did not include all resonance structures for benzene they also include certain bicyclo compounds
I don't follow. Benzene is not a bicyclo molecule
How many resonance forms are possible (which delocalize, or move the charge): Ph-CH2+
(Ph is phenol)?

What is keep electron place in always change
I don't understand the question. Could you clarify what you're asking?

why we convert the green bond to lone pair?
I don’t know which exact example you’re referring to, but the idea is that a pi bond is a source of electrons which are delocalized. These electrons can move around the molecule to form various resonance structures. They can rest on an atom as a lone pair or form new pi bonds in other locations.

interestingly beautiful videos
You are so kind, thanks so much.
why is the nitrogen positive and oxygen negative in nitro
Amana Prateek
oxygen is more electronegative than nitrogen
These are the formal charges and have to do with how many electrons each atom has around it. I teach formal charges in detail here: leah4sci.com/formal-charge-formula-shortcut-for-organic-compounds-video/
