Q. Which of the following carboxylic acids undergoes decarboxylation easily?
AMUAMU 2013Aldehydes Ketones and Carboxylic Acids
Solution:
If keto group is at $\beta$-position then decarboxylation takes place simply by heating, $\beta$ -keto acid is very reactive in decarboxylation reaction because it produces a highly stable carbanion.
