Question

Phenol and benzoic acid may be distinguished by (A)  NaHCO3 (B)  NaOH  (C)  Na  (D)  PCl3

Tardigrade Admin · Accepted Answer

Phenol and benzoic acid can be distinguished by NaHCO 3 because being stronger acid only benzoic acid reacts with it and phenol does not react. Effervescences of CO 2 confirms presence of COOH group.

Phenol and benzoic acid react with other reagents ( NaOH , Na , PCl 5. ) given as choices. So, they cannot be used to distinguish them.
