(a)

Interpretation Introduction

Interpretation: The formula of conjugate acid of base dimethylamide should be written.

Concept introduction: In accordance with Bronsted definition, an acid act as proton donor and a base can act as proton acceptor. Thus, in a typical acid-base reaction, the fundamental principle is a lone pair of base reaches out for an acidic proton. Similarly, curved arrows are used for departing conjugate base. After deprotonation, the species left with negative charge is refers as conjugate base of acid while the other with positive charge is termed conjugate acid of given base. For example:

  

The strength of various conjugate acid-base pairs varies inversely to one another; the strong acid has weak conjugate base and strong base has weak conjugate acid and vice-versa.
