a.

Interpretation Introduction

Interpretation: Whether ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{OCH}}_{\text{3}}{\text{CH}}_{\text{2}}$ exhibits molecular dipole moment or not should be identified and if it does then the direction of the net molecular dipole moment must be indicated.

Concept Introduction: The arrangement of electron pairs is identified according to VSEPR (Valence Shell Electron Pair Repulsion) theory wherein all the electron pairs are aligned in such a way that they are at maximum distance from each other. The structure of every molecule in VSEPR is explained by considering the steric number (combination of lone pairs and $\text{σ}$ -bonds involved in molecule).
