Which is more bond lenght alkanehalide and arryl halide?

1.	Which is more bond lenght alkanehalide and arryl halide?
Answer» Aryl HALIDES have PARTIAL double bond character because of the resonance of the lone pair of the halide with the BENZENE ring, and thus the bond energy of aryl halides is GREATER as compared to alkyl halides. Hence, the (C-X) bond is HARDER to break in aryl halides than in alkyl halides, and therefore aryl halides are less reactive than alkyl halides.
