Question

Reaction of HBr with propene in the presence of peroxide gives.
a) isopropyl bromide
b)3-bromo propane
c)ally bromide
d)n-propyl bromide

Answer 1

In propene on reaction with HBr can lead to the formation of 1 bromopropane(npropylbromide) or 2 bromopropane (iso propyl bromide)

But the presence of H2O2 leads to the antimarkonikov addition(addition of Br on the C having more no of H) of Br

This leads to the formation of 1 bromopropane means n propyl bromide
