Chapter 4, Problem 17E

Interpretation Introduction

Interpretation: Acid-base reactions between each pair of reactants should be determined with the help of curved arrows.

Concept introduction: According to Lewis's concept, substance that donates electron pair is termed as base while that accepts or gains electron pair is called acid. For example, ${\text{BF}}_{\text{3}}$ is electron-deficient compound and can easily accept electrons so it is Lewis acid. But ${\text{NH}}_{\text{3}}$ has lone pair of electrons that it can donate easily so it acts as Lewis base.
