Chapter 16, Problem 16.47CP

Interpretation Introduction

Interpretation:

The electron-dot structure for the products and reactants of ${\text{PCl}}_{\text{4}}$ and ${\text{Cl}}^{-}$ needs to be determined using the curved arrow.

Concept introduction:

A substance which donatesan electronic pair is known as Lewis base and substance which accepts electronic pair is known as Lewis acid.

All cations accept electrons and act as Lewis acids. For example,Copper $\left({\text{Cu}}_{\text{2}}\right)$, Iron $\left({\text{Fe}}^{\text{2+}}{\text{orFe}}^{\text{3+}}\right)$ and hydrogen ion $\left({\text{H}}^{\text{+}}\right)$.
