The general structural difference between a carboxylic acid and an ester is the same as that between an

Question

Quizplus · Accepted Answer

Both a carboxylic acid and an ester contain a carbonyl group (C=O), but the carboxylic acid also contains a hydroxyl group (-OH) while the ester contains an alkyl group (-R). This difference in functional groups is analogous to the difference between an aldehyde and a ketone, as well as an alcohol and an ether. Therefore, options A and B are partially correct, but not completely, while option C is not relevant to the question. Option D correctly identifies that there is more than one correct response.
