Question

Benzoic acid decarboxylation which acid decarboxylate easily

Answer 1

Beta-keto carboxylic acids (like Acetoacetic acid) and dicarboxylic acids tend to decompose directly on heating.
This is because:
1.Stabilized carbanion formation (if the carboxylate as opposed to the acid decarboxylates)
2. H- bonding makes it easy to transfer acidic H into the ketone oxygen, and eliminate CO2, forming an enol that tautomerizes.

Answer 2

Explanation:

$<p style ="Color:yellow; font-family: cursive; background:black;font size25px;"> Carboxylic acids loss carbon dioxide to form hydrocarbons when their sodium sulphate are heated with soda lime . This reaction is called decarboxylation.$
