Chapter 16, Problem 16.86QP

Interpretation Introduction

Interpretation:

Whether the given reaction is a Lewis acid or a Lewis base has to be identified.

Concept Introduction:

According to Lewis theory, acid and base can be defined as follows.

Lewis Acid:

Lewis acid is a substance that can accept a pair of electrons

Example: $\text{BF}{\text{3}}_{}$

Lewis Base:

Lewis base is a substance that can donate a pair of electrons.

Example: ${\text{NH}}_{\text{3}}$

The Lewis acid-bas reaction:

The Lewis acid is an electron pair acceptor and Lewis base is an electron-pair donor.
