Chapter 16, Problem 16.27UKC

Interpretation Introduction

Interpretation:

The strongest and weakest base should be determined from the given amines.

Concept introduction:

Amines are the derivatives of ammonia $\left(N{H}_3\right)$ with one or more of the hydrogens replaced with a substituent such as an alkyl group.

Due to ability of lone pair in the nitrogen atom to accept a proton, amines are weak base in nature.

Factors that affect the basicity of amines are listed below,

Substitution by alkyl groups

The presence of alkyl groups (electron donating group) such as $-C{H}_{3}and-C_2{H}_5$  will make the amine become more basic.

Substitution by electron-withdrawing groups

The presence of electron-withdrawing groups or atom will decrease the basicity.
