(a)

Interpretation Introduction

Interpretation:

Lewis structure with minimal formal charges for ${\text{POCl}}_{\text{3}}$ has to be written.

Concept Introduction:

Formal charge: The formal charge is defined as the charge carried by an atom in a molecule assuming that, irrespective of the relative electronegativity of the shared atoms, all the chemical bonds are shared equally between the two atoms.

Formal Charge: The formal charge on atoms in the Lewis structure is calculated by the equation below.

$\text{Formal}\text{charge}\left(\text{F}\text{C}\right)\text{=}\left(\begin{array}{l}\text{no}\text{.of}\text{valence}\\ \text{electron}\text{in}\text{atom}\end{array}\right)-\frac{\text{1}}{\text{2}}\left(\begin{array}{l}\text{no}\text{.of}\text{bonding}\\ \text{electrons}\end{array}\right)-\left(\begin{array}{l}\text{no}\text{.of}\text{non-bonding}\\ \text{electrons}\end{array}\right)$

Lewis structure: The bonding between atoms in a molecule satisfies the octet rule of valence electrons and the lone pairs also exist in the molecule. The electron is represented as dot.
