Vedclass · Answer

(B) The reaction of propylbenzene $(C_6H_5-CH_2-CH_2-CH_3)$ with bromine $(Br_2)$ in the presence of light $(h
u)$ and heat is a free radical substitution reaction.In alkylbenzenes,the benzylic hydrogen is the most reactive due to the stability of the resulting benzylic radical.The benzylic radical is stabilized by resonance with the benzene ring.Therefore,the bromine atom replaces the hydrogen atom at the benzylic position (the carbon atom directly attached to the benzene ring).Thus,the product formed is $1$-phenyl-$1$-bromopropane,which is $C_6H_5-CH(Br)-CH_2-CH_3$.
