the key ingredients of vinegar are organic compounds whose functional groups
belong to which category?
a) alkyl halide
b) ester
c) amide
d) alcohol
e) carboxylic acid

Explanation:

Vinegar is mainly acetic acid (\(CH_3COOH\)). The functional group of acetic acid is the carboxyl group (\(-COOH\)), which belongs to carboxylic acids. Alkyl halides have \( -X\) (where \(X = F, Cl, Br, I\)) as the functional group. Esters have \( -COO-\) as the functional group. Amides have \( -CONH_2\) (or related derivatives) as the functional group. Alcohols have \( -OH\) (hydroxyl group not attached to a carbonyl carbon in the case of carboxylic - acid distinction) as the functional group.

Answer:

e) carboxylic acid
