Reference: AQA
A structure in which the acidic hydrogen is replaced with an alkyl group, giving R-COO-R′, with the C=O staying put and the second alkyl group hanging off the single-bonded oxygen.
The repeat unit contains the ester group –COO–, with the carbonyl carbon coming from the acid and the oxygen from the alcohol.
