You're such an angel for teaching us resonance in an entertaining yet easy-to-digest way. :) And it's nice that we share the same name. Thank you Leah!
The moment you realize that rhino is a baby of Dino and unicorn... say whaaaat? 😳 that is some mad science right there! 😂😂😂😂 Thank you for great videos! Learning should be fun! Love your Chanel!
I may be missing something crucial here, but I don't understand why we only have 2 resonance structures. Couldn't the pi bond inside the benzene just "jump" around to all the bonds? Why only once and why only toward the carbon with the ethyl group to cause the chain reaction of that bond breaking and causing the addition of the lone pair onto the 1st ethyl carbon? You know what, I just answered my own question by typing that out. I'm going to post it in case it helps anyone else. You even say this in the video, but it's because the charge has to be conserved. If we move that purple double bond to anywhere not touching carbon 1 (the one with the ethyl substituent) then we won't get that green lone pair jumping off and we'll create a carbocation without anything having a negative charge to balance it out. Same reason we can't put the double bond from C1 to C6 (if numbered counterclockwise starting with the substituent). If we did we would still cause green to jump and have the lone pairs and 1 minus charge, but C2 AND C3 would now be carbcations and again our charge wouldn't be conserved. Wow, thank you for this space as a sounding board. It's so hard with remote learning, sometimes you just need to talk something out, even if it's screaming into the void that is the YT comment section.
Also, you even said not to resonate sp3 carbons. I'm just literally the dumbest person ever and had to circular logic my way there. Why am I like this ugh. Thanks for the video.
5.22 Isn't it 6-7=-1 since oxygen formed a dative bond with carbon? Although that one electron is not directly attached to oxygen atom,it still came from oxygen
No, the formal charge of the oxygen in discussion at 5:22 is zero. We are only looking at the electrons’ placement at that point in time. Notice that the -1 charge resonates between the two oxygens. In the first structure, the bottom-most oxygen had the charge. In the second structure, the top-most oxygen had the charge. When we look at the molecule overall, both oxygens hold some portion of the negative charge. Thanks for watching and commenting!
thankyou this video helped me a lot the explaination is so cool when compared to my sir's explaination i really thank u a lot THANKYOU so much..... Leah Fisch
This is explained better in 10 minutes than my professor could explain with an entire textbook! Thank you!
You're welcome! Glad to help! :)

You're welcome, so happy to help! And awesome name :)
Thank you Leah! Two days from now I will be having my prelim exam for orgo and your videos really helped me a lot.
So happy I could help!
I just found these and I wanted to say thank you. I requested your ebook and look forward to learning more this semester.
You're very welcome!

Haha too funny! You're very welcome. I'm glad you are enjoying the channel!
Very helpful, thanks!
You're very welcome.
thank thank u , makes more sense.
You're very welcome!

Thanks for sharing what you realized with others!
You are definitely NOT dumb! Orgo is tough, but you're tougher!

Very cool explanation.
Glad you like it!
Shouldn't the electrons be 5 on each oxygen to make 10 as they should be evenly distributed?
At which specific point in the video?
Love the content.
Thank you!
Literally the best video on this stuff can you be my teacher please!
Oh wow, thanks so much!
thankyou this video helped me a lot
the explaination is so cool when compared to my sir's explaination
i really thank u a lot
THANKYOU so much..... Leah Fisch
You're so welcome, happy to help!
U the best!!!
Thank you!
This video is great and I love your teaching but damn this sounds like a mouth noise ASMR. Can you move the mic like a few cm away from your mouth? :)
Thanks for your suggestion, I appreciate it!
