AIIMS 2014 Chemistry Carboxylic acids MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following carboxylic acids undergoes decarboxylation easily?
A
C6H5COCOOH
B
C6H5COCH2COOH
C
C6H5CHOHCOOH
D
C6H5CHCOOH NH2
Correct Answer
Option B
Detailed Explanation
The correct answer is B) C6H5COCH2COOH because it contains a carbonyl group adjacent to the carboxylic acid, which stabilizes the resulting carbanion during the decarboxylation process. This stabilization through resonance facilitates the loss of carbon dioxide (CO2), making the decarboxylation reaction more favorable compared to the other options, which lack this structural feature.
