Text Solution

Verified by Experts


The major product of the bromination of ethyl benzene is
It is a photochemical reaction and proceeds by free radical mechanism. Actually, there are two possible free radicals which are initially formed when `Br_(2)` attacks the given substrate.

The free radical (II) is a benzylic free radical and is resonance stabilised.

The free radical (I) is comparatively less stabilised by resonance.

therefore, the major product of bromination is 1-bromophenylethane.
