(a)

Interpretation Introduction

Interpretation: The given molecules ${\text{CH}}_{\text{2}}{\text{Cl}}_{\text{2}}$ and ${\text{XeF}}_{\text{4}}$ are polar or not should be determined.

Concept introduction:

• Polarity of a bond is due to the difference in electro-negativities of atoms presented in it. The polarities of bonds are represented by using vectors.
• If the result of all bond polarities or vector sum is non-zero in a molecule, then the molecule is called as polar molecule.
• If the result of all bond polarities or vector sum is zero in a molecule, then the molecule is called as nonpolar molecule.
• Parallel vectors will give non-zero values and
