Chapter 14, Problem 14.67P

Interpretation Introduction

Interpretation:

Based on the relative sizes of $\text{F}$ and $\text{Cl}$, the structure of ${\text{PF}}_{\text{2}}{\text{Cl}}_{\text{3}}$ has to be predicted.

Concept Introduction:

Atomic radius and size:

The distance between the outer most electrons to centre of nucleus is known as atomic radius, if atomic radius is large means size of the atom also small and if atomic radius is large means size of the atom also small.
