Question

Quizplus · Accepted Answer

The functional group circled in the molecule is a carbonyl group consisting of a carbon atom double-bonded to an oxygen atom. Since the carbonyl group is located at the end of the chain, it is classified as an aldehyde. Glucose has six carbon atoms, and hence it is classified as an aldohexose.
