A. -CHO✓ Correct Answer
B. -COOH
C. -OH
D. -CO-
💡 Solution & Explanation
Aldehydes are characterized by the presence of a terminal carbonyl group attached to at least one hydrogen atom, universally represented by the structural formula minus CHO. Conversely, the functional group minus COOH defines carboxylic acids, while minus OH designates alcohols and minus CO minus represents ketones. Carbonyl compounds form a vast class of organic molecules widely encountered in biochemistry and synthetic industrial chemistry.
