Predict the direction and the relative value of the dipole moment of the following bond:

(A) C←Cl, electronegativity difference > 0.5

(B) C←Cl, electronegativity difference < 0.5

(C) C→Cl, electronegativity difference > 0.5

(D) C→Cl, electronegativity difference < 0.5

The direction of dipole moment is C→Cl and electronegativity difference = 0.5

Explanation:

The dipole moment is formed when there is a separation of charges in a chemical bond. The electrons of the bond tend to be more localized near the more electronegative atom.

The electronegativity of chlorine atom = 3.0 and electronegativity of carbon atom = 2.5

Therefore, chlorine is more electronegative than carbon. So, the electrons tend to be localized more near the electronegative chlorine atom. Therefore, the direction of dipole moment is C→Cl and electronegativity difference is equal to 0.5.
