Which functional group is found in esters?
–COO–
Esters have the general formula R–COO–R′, formed when a carboxylic acid reacts with an alcohol (esterification).
Their characteristic functional group is the ester linkage –COO–. –COOH is the carboxylic acid group, –NH2 is the amino group and –OH is the hydroxyl (alcohol) group.
Hence, the answer is –COO–.
