Question

Difference between chlorobenzene and cyclohexyl chloride structure

Answer 1

CHLOROBENZENE:: when benzene reacts with excess of chlorine in presence of anhydrous AlCl3 , hexachlorobenzene is obtained. All the six hydrogen atoms of benzene ring are replaced the electrophile Cl ions. 

Cyclohexyl Chloride::: Benzene on heating with hydrogen at 458 K to 473 K in the presence of the Ni catalyst forms Cyclohexyl.

Answer 2

Answer: The dipole moment of chlorobenzene is less than cyclo hexyl chloride as in chloro benzene C-Cl bond is sp2 hybridised where as in cyclohexyl chloride the C_cl bond is Sp3 Hybridised . as sp2 has more s character and more electronegative than sp3. Chlorobenzene is less polar than cyclohexyl chloride.
