Give Reason : The dipole moment of Chlorobenzene is lower than that of cyclohexyl chloride. Why?
Dear student,
Dipole moment between two atoms arises due to a large difference in electronegativity between the two atoms. In the case of Chlorobenzene, the carbon in the C-Cl bond is sp hybridized and so carbon has greater value of electronegativity, and thus, the electronegativity difference is less. Whereas, in the case of cyclohexyl chloride, the carbon in C-Cl bond is so hybridized whose electronegativity value is very less as compared to the sp2 carbon . Thus, due to the large electronegativity difference, the dipole moment is also more in the case of cyclohexyl chloride than in chlorobenzene.
Regards.
