Vedclass · Answer

(A) In haloarenes, the $C-Cl$ bond acquires partial double bond character due to resonance between the lone pair of electrons on the chlorine atom and the $\pi$-electron system of the benzene ring.This partial double bond character results in a shorter bond length compared to the pure single $C-Cl$ bond found in haloalkanes.The bond length of $C-Cl$ in chlorobenzene (haloarene) is approximately $169 \ pm$, while in chloromethane (haloalkane) it is approximately $177 \ pm$.Therefore, the correct order is $169 \ pm$ and $177 \ pm$.

The $C-Cl$ bond lengths (in $pm$) in haloarene and haloalkane are respectively:
