Reactivity of chlorobenzene is

A) less than benzyl chloride

B) more than ethyl bromide

C) equal to methyl chloride

D) more than isopropyi chloride

Correct Answer: A

Solution :

[a]

Chlorobenzene is less reactive than benzyl chloride due to resonance. The \[CCl\] bond of chlorobenzene acquires double bond character due to resonance.

As a result, double bond become strong and thus difficult to break.

Hence, chlorobenzene is not very reactive. In case of benzyl chloride, it is resonance stabilised. Hence it is more reactive.
