Which statement is true about propanal?

Recognizing functional groups in organic molecules is what this item tests. Propanal has an aldehyde functional group. This is evident from its terminal carbonyl group, written as CH3-CH2-CHO. The carbonyl carbon is double-bonded to oxygen and bonded to a hydrogen, which is the signature arrangement for aldehydes. Because of this, the molecule is an aldehyde rather than a ketone (which would have the carbonyl carbon bonded to two carbon groups), an ether (which would have an O linking two carbons), or an alcohol (which would have an -OH group). Propanal is also known as propionaldehyde.
