Glutaric acid is the common name for:
AHexanedioic acid (adipic acid)
BButanedioic acid (HOOC-(CH₂)₂-COOH)
CPentanedioic acid: HOOC-(CH₂)₃-COOH
DPropanedioic acid (malonic acid)
Answer & Solution
Correct answer: C. Pentanedioic acid: HOOC-(CH₂)₃-COOH
Common names for dicarboxylic acids: **oxalic = ethanedioic (HOOC-COOH)**; **malonic = propanedioic**; **succinic = butanedioic**; **glutaric = pentanedioic**; **adipic = hexanedioic**. Memory aid: O-M-S-G-A for the first 5 (2-6 carbons).
