प्रश्न
Given reasons: C–Cl bond length in chlorobenzene is shorter than C–Cl bond length in CH3–Cl.

उत्तर
In chlorobenzene, the C−Cl bond gets partial double bond character because of the +M effect shown by the Cl group. Due to double bond character, the bond length decreases in chlorobenzene as compared to the normal CH3−Cl bond length. Therefore, the C–Cl bond length in chlorobenzene is shorter than the C–Cl bond length in CH3–Cl.
