검증된 단계별 안내1
Identify the functional group of a ketone, which is characterized by a carbonyl group (C=O).
Recall that in a ketone, the carbon atom of the carbonyl group is bonded to two other atoms or groups.
Understand that in ketones, the carbonyl carbon is bonded to two carbon atoms, not hydrogen or nitrogen.
Contrast this with aldehydes, where the carbonyl carbon is bonded to at least one hydrogen atom.
Therefore, the atom directly bonded to the carbon atom of the C=O group in a ketone is another carbon atom.
