Compound(s) which will liberate carbon dioxide with sodium bicarbonate solution is/are :

Options

  1. AA and B only
  2. BB and C only
  3. CC only
  4. DB only

Correct answer

B. B and C only

Step-by-step solution

Compounds which are more acidic then H 2 CO 3 , gives CO 2 gas on reaction with NaHCO 3 . Compound B i.e. Benzoic acid and compound C i.e. picric acid both are more acidic than H 2 CO 3 . equilibrium favours forward direction and CO 2 ↑ is liberated. Equilibrium favours backward direction and CO 2 ↑ is not liberated.
