Thank you for recognizing that. I used to be so overwhelmed because I was taught to memorize, and so I try to take that frustration away by showing you WHY. :)

I'm wondering why did the reaction initiates with bromine not hydrogen?? Thank you is not enough...your videos really helped me
@Leah4sci Жыл бұрын
You're so welcome! The oxide radical grabs the hydrogen from HBr to create a very stable alcohol molecule. (The alternative would be to bond the oxygen to the bromine, and that is not energetically favorable.) That leaves a bromine radical to initiate the radical halogenation. For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/

You should try solving organic chemistry of JEE Mains/Advanced it will surely boggle your mind.

So H should go on the most stable (substituted) carbon?
@Leah4sci4 ай бұрын
Yes, you can think of it that way. The radical intermediate will form on the most substituted carbon of the pi bond after reaching for a bromine radical in solution. That leaves the more substituted position available for the H of the HBr reagent.
