General Formula
They are denoted by RCOOR where R may be any alkyl group. The alkyl groups of ester may be similar or different. The general formula of ester is
CnH2n+1 – COO – CnH2n+1
Where n may be any natural number.
Structure
The structural formula of ester shows that it contains a Carbonyl group.
RCOOR
Examples
