Question

Maximum decarboxylation occurs in:

Options

• CH₃COOH

• C₆H₃COOH

• C₆H₅CH₂COOH

• CH₃COCH₂COOH

Answer 1

CH₃COCH₂COOH

Explanation:

β-keto acid is CH₃COCH₂COOH. Thus, maximum decarboxylation occurs in carboxylic acids containing an electron-withdrawing group, such as > CO `oo` – COOH at the -carbon atom with respect to the – COOH group.
