Chapter 22, Problem 30P

Interpretation Introduction

Interpretation: The nitrogen atom that is more basic in $4-\left(N,N\text{-dimethylamino}\right)\text{pyridine}$ is to be identified.

Concept introduction:

According to Lewis acid-base theory, the compounds which can donate its lone pair of electron are termed as bases and the electron acceptors are known as acids. Amines acts like a base as the nitrogen atom contains one lone pair of electrons.

Most of the organic structures cannot be represented using single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures. These resonance structure combine together to give resonance hybrid that is lower in energy and is the most stable structure.
