Givereasons : C-Cl bond length in chlorobenzene is shorter than C -- – InterviewSolution

1.	Givereasons : C-Cl bond length in chlorobenzene is shorter than C -- Cl bond length in CH_(3) - Cl .
Answer» SOLUTION : Electrons on Cl in chlorobenzene TAKE part in resonance with the BENZENE ring. This creates a partial double BOND character between C and Cl. This does not happen in methyl chloride. A double bond is shorter than single bond.
