Vedclass · Accepted Answer

Formation of $A$ is an electrophilic addition reaction and formation of $B$ is a free radical addition reaction.

Vedclass · Answer

(A) The reaction of styrene with $HBr$ in the absence of peroxides (or light) follows Markovnikov's rule,which is an electrophilic addition reaction,yielding $1$-bromo-$1$-phenylethane $(A)$.In the presence of light $(h
u)$,the reaction follows the anti-Markovnikov addition (peroxide effect/free radical mechanism),yielding $1$-bromo-$2$-phenylethane $(B)$.Thus,the formation of $A$ is an electrophilic addition reaction,and the formation of $B$ is a free radical addition reaction.

Analyze the following reaction and identify the nature of $A$ and $B$.
