Quizplus · Accepted Answer

An ester functional group has the structure RCOOR', where R and R' are organic groups. The given structure C-O-C is a typical ether functional group. However, in this case, the C atom is also attached to an O atom through a double bond, which makes it a carbonyl group. When an ether functional group is attached to a carbonyl group, it forms an ester functional group. Therefore, the correct answer is (A) ester.
