What's a stronger base, a normal pyrrole or imidazole? I'm seeing people on reddit/the internet say it's the imidazole, but wouldn't it be more stable by resonance? They are both aromatic. Thanks
They are correct as it is the imidazole. The lone pair on the nitrogen in pyrrole is part of the aromatic pi system and very stable. But imidazole has 2 nitrogen atoms. The lone pair on 1 is part of the aromatic pi system and is also very stable. But the lone pair on the second nitrogen is in an sp2 hybrid orbital and is NOT part of the aromatic pi system. This lone pair is considerably less stable and more basic. Hope this helps!
Thank you so much!! I’m kinda lost when it comes to Organic Chemistry but your video helped a lot!
Excellent, Michelle!
Actually just cleared up my largest confusion in Ochem - tysm
Excellent - you're welcome!
Thank you so much
This was really useful and perfectly explained
The pase was perfect
Thank you so much ❤
You're welcome and Thank You!
excellent video really helped in basicity explanations
Glad to hear it!
this was good review right before my final thx
Best on your final!

chad i love u i swear i would be so gone in organic chem if it wasnt for u
Glad the videos are helpful!
Where in order of importance is the inductive effect of electron donating/withdrawing groups?
thanks sir it was really helpful!
You're welcome, Dinish!
It's fantastic
But pls explain further
Sir this is nice but may you please slow down a bit ..you're a bit fast
I get that a lot - my best souggestion is to slow down the playback to the speed that works best for you. Hope that helps!
thank you !
You're welcome!
