Question

What would be the product when propene reacts with hbr in presence of organic peroxide?

Answer 1

This is known as Markovnikov's Rule. Because the HBr adds on the "wrong way around " in the presence of organic peroxides, this is often known as the peroxide effect or anti-Markovnikov addition. In the absence of peroxides, hydrogen bromide addsto propene via an electrophilic addition mechanism.

Answer 2

hello... ☺

presence of organic peroxides is  peroxide... or  or anti-Markovnikov addition....

In the absence of peroxides, hydrogen bromide adds to propene.....

thank you ☺
