Question

Explain why the dipole moment of chlorobenzene is lower than that of cyclohexylchloride

Answer 1

Hence chlorobenzene is more electronegative than cyclohexyl chloride. Therefore, the density of electrons C-Cl bond at chlorine atom is less in chlorobenzene than cyclohexyl chloride. Due to this polarity of the C-Cl bond decreases and hence dipole moment of chlorobenzene is lower than cyclohexyl chloride
