Need help with Orgo? Download my free guide ’10 Secrets to Acing Organic Chemistry’ HERE: leah4sci.com/o...
In this video, you’ll learn how the radical halogenation of an alkene in the presence of peroxides differs from the typical hydrohalogenation alkene addition reaction. You’ll learn how to apply initiation and propagation steps of the radical mechanism, how to identify the most stable intermediate, and understand why the anti-Markovnikov product is favored.
You’ll also learn about the stereochemistry of alkene radical halogenation.

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
@Leah4sci Год назад
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.

I've heard it's tough, but many JEE students use my resources to help them as they prepare. Hope this helps you, too!

So H should go on the most stable (substituted) carbon?
@Leah4sci
@Leah4sci 5 месяцев назад
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.
