Question

The dipole moment of chloro benzene is lower than that of cyclohexyl chloride.
Why?

Answer 1

It is due to electron with drawing effect of phenyl group which decrease dipole
moment of chloro benzene.

Answer 2

Answer:

Explanation:

The dipole moment of chlorobenzene is less than cyclohexyl chloride as in chloro benzene because C-Cl bond is sp2 hybridised where as in cyclohexyl chloride the C-Cl bond is SP3 Hybridised . Since sp2 has more s character and more electronegative than sp3. ... Hence, chlorobenzene is less polar than cyclohexyl chloride.
