Step-by-step solution

The reaction of ethylbenzene with excess Cl₂ in the presence of hv (ultraviolet light) is a free radical substitution reaction. The reaction occurs at the benzylic position because the resulting benzylic radical is resonance-stabilized by the benzene ring. The first step involves the abstraction of a hydrogen atom from the benzylic carbon ( CH₂ ) to form a 1-phenylethyl radical, which then reacts with Cl₂ to form 1-chloro-1-phenylethane. Since the reagent Cl₂ is in excess, the reaction continues at the same benzyli
