What is the product of decarboxylation of anhydrous sodium benzoate?

Options

  1. ABenzene
  2. BCyclohexane
  3. CBenzene hexachloride
  4. DChlorobenzene

Correct answer

A. Benzene

Step-by-step solution

Decarboxylation of anhydrous sodium benzoate is carried out by heating it with soda lime, which is a mixture of sodium hydroxide and calcium oxide. The reaction proceeds as follows: C₆H₅COONa + NaOH CaO, C₆H₆ + Na₂CO₃ The main product formed in this reaction is benzene. Answer: Benzene
