Q.

As compared with chlorocyclohexane, which of the following statements correctly apply to chlorobenzene

A. The magnitude of negative charge is more on chlorine atom.
B. The C–Cl bond has partial double bond character.
C. C–Cl bond is less polar.
D. C–Cl bond is longer due to repulsion between delocalised electrons of the aromatic ring and lone pairs of electrons of chlorine.
E. The C–Cl bond is formed using sp2 hybridised orbital of carbon.

Chlorocyclohexane is more polar due to I effect of Cl,

Whereas chlorobenzene has I>+M, so it is less polar & also has partial double bond character.
