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
That's great!
You're welcome! Glad to help! :)
You deserve more recognition on RUclips.
Awwww, thank you so much!
I rate you a 100%. I've been spending more time on RUclips trying to understand resonance but in your video I understood in less than 5 minutes. You're the best
Wow, happy to help! Thanks so much for the compliments.
This never made sense to me until now, your videos are so helpful, thank you!! 🙌🏼
Glad it helped! You're welcome
You are amazing! Your calming voice explaining chemistry is simply wow! Greetings from an Italian uni student :)
Wow, thank you!
amazing as a teacher you deserve high appreciate i really respectful you and your effort made on such videos
Aww thanks for your kind words!
you just made something near impossible for me possible. thank you . keep up the great work
Wow, you're so welcome!
Amazing session!!! I just clearly understood this !!!
Glad it was helpful!
Wish I’d found this earlier!
Better late than never!
Thnxxxxxxxxxxxxxxx a lot ! Finally I understood that what actually resonance is ! Thnkuuuuuuuuuuu sooooo much Miss!:)
You're so welcome, happy to help!
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
You're welcome! Glad to help! :)
Thanku so much mam, I have no words to appreciate your hard work. Love you from India. May Allah bless you
You're very welcome.
The best lecture of chemistry in my life thanks a lot
Glad you enjoyed it
Finally someone Who actually explained this...! thankyou
You're so welcome, I'm happy to help!
SOOOO GOOD WITH THE COOR CODE!!!super helpful!!
Yay! Thank you!
Another excellent video, thanks.
You're very welcome!
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!
Thannnnk you
Really you explained it very well ..💪🏻❤
You're so welcome!
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
Glad you started watching now, happy to help!
Thanks ma'am
This video was informative.
I'm glad it helped
you r a very good organic teachr good job :*
Thank you!
I'm gonna like this video on all my other 100 accounts
Thanks! Glad you liked it.
Thank you very much !! This is helpful
I'm so glad. You're welcome!
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.
Fantastic explanation thanks a lot
You're welcome! :)
very well explained... thnku so muchh..
You're welcome, happy to help!
How many resonance forms are possible (which delocalize, or move the charge): Ph-CH2+
(Ph is phenol)?
I'm sorry, but I don't offer tutoring through RUclips comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
my brain and I love you soooo much😭❤️
Awww, thanks so much!
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/
really nicely explained
Glad you liked it
very nicely explained keep going
Thanks, still at it 6 years later!
Thanku so much , this topic was a pain in my...
you're welcome! glad to help!
Oh thank god there are good teachers in the internet
Thanks! Glad to help!
How does the positive charge in N and negative charge in O occur? @Leah4sci
At which specific point in the video? (timestamp please)
disciple me!! I started loving the chemistry
WOOHOO!!!
God bless you
Thank you!
I dont understand why the double bound between oxygen and nitrogen breaks, the formal charge is right or am I wrong?

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.
keep up the good work best wishes from me😁
Thank you!
best video on this topic may Allah bless u!
Thank you so much!
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.
@@Leah4sci yeapp thats what i meant, thank you !

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. For more information on this topic, watch my series at leah4sci.com/resonance
Thank q very very much mam
You're welcome 😊
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
What is keep electron place in always change
I don't understand the question. Could you clarify what you're asking?
Can u tell me why benzene shows resonance

answer of the last one - multi substituted benzene?
at which point of the video please?
@@Leah4sci 14:53
@@Leah4sci By the way thanks for the tutorial. It really helped me a lot
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/
But NO2 has a negative charge
Which point in the video are you referring to?
Wow
Glad you like it!
I like video
I'm happy to hear that :)
Hi Leah how r u

Mam you're so cute!!, can I know which country you belonged
Can you please tell it in hindi
I appreciate the feedback, but I don't have any plans to start teaching in Hindi
you saved my ass
And hopefully all the rest of you, too! :)
