검증된 단계별 안내1
Identify the molecular formula given: CH\_3CH\_O. This suggests a two-carbon structure with a CH\_3 (methyl) group and a CHO group attached.
Recognize that the CHO group represents an aldehyde functional group, characterized by a carbonyl (C=O) bonded to a hydrogen atom.
Recall that a methyl group (CH\_3) is a simple alkyl group attached to the rest of the molecule.
Compare the functional groups present: the molecule contains an aldehyde group (CHO) and a methyl group (CH\_3).
Conclude that the correct functional groups present in the molecule are aldehyde and methyl.
