Question

The compound that does not liberate CO2 , on treatment with aqueous sodium bicarbonate solution, is (A) Benzoic acid (B) Benzenesulphonic acid (C) Salicylic acid (D) Carbolic acid (Phenol)

Tardigrade Admin · Accepted Answer

Compounds with -COOH group or - SO3H group can liberate CO2 with NaHCO3 solution as they are more acidic than carbonic acid. As phenol is less acidic than carbonic acid so cannot give this test.

Q. The compound that does not liberate $C O_{2}$ , on treatment with aqueous sodium bicarbonate solution, is

Benzoic acid

Benzenesulphonic acid

Salicylic acid

Carbolic acid (Phenol)

Compounds with -COOH group or - $S O_{3} H$ group can liberate $C O_{2}$ with $N a H C O_{3}$ solution as they are more acidic than carbonic acid. As phenol is less acidic than carbonic acid so cannot give this test.
