Sodium Benzoate on reacting with soda lime forms:
Correct answer: B. Benzene
- A. Benzoic Acid
- B. Benzene
- C. Toluene
- D. Benzaldehyde
Explanation
Sodium benzoate undergoes decarboxylation when heated with soda lime (NaOH + CaO). The -COONa group is removed as CO2, leaving behind toluene (C6H5CH3).This is a classic example of alkali-induced decarboxylation of a carboxylate salt.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
