Question

(i) Chlorobenzene is less reactive than chloromethane.

Answer 1

Answer:

In chlorobenzene the electron pairs are in conjugation with pi electrons of the ring. Thus, C-Cl bond accquires a partial double bond character due to resonance. As a result, the bond cleavage in haloarene is diffcult than chloromethane.

or

In chlorobenzene delocalization of the electrons of C - Cl bond and a partial double bond character develops in the bond, which makes it difficult for the Nucleophile to cleave the C - Cl bond.......
