- (a)
- (b)
- (c)
- None of these
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Formula / Definition}
\[ \beta\text{-keto acid} \xrightarrow{\Delta} \text{Decarboxylation} \]
Step 2: Calculation / Simplification}
The \(-\mathrm{COOH}\) directly on the ring is \(\beta\) to the ring ketone.
Heating eliminates this specific carboxyl group as \(\mathrm{CO_2}\).
The side chain \(-\mathrm{CH_2COOH}\) remains intact.
Step 3: Final Answer
\[ \text{Option (c)} \]
\[ \beta\text{-keto acid} \xrightarrow{\Delta} \text{Decarboxylation} \]
Step 2: Calculation / Simplification}
