Chapter 1.3, Problem 1.12P

Interpretation Introduction

Interpretation:

The structural formulas for four esters with the molecular formula ${\text{C}}_4{\text{H}}_8{\text{O}}_2$ has to be drawn

Concept introduction:

Isomer: A molecule having same molecular formula with different chemical formula is called isomer.

Carboxylic ester:

A carbon atom is double-bonded to an oxygen atom $(C=O)$ is called as carbonyl group which is one of the functional group.

If the carbonyl carbon is attached with hydroxyl group is called as carboxylic acid. Hydrogen atom is replaced with carbon atom in carboxylic acid is called as ester.
