Question

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

• A. 2 and 3 only
• B. 1 only
• C. 2 only
• D. 3 only

Answer 1

The correct option is A 2 and 3 only

Compounds that are more acidic than $H_{2}C{O}_3,$ gives $C{O}_2$ gas in reaction with $NaHC{O}_3.$ Compound 2 i.e. benzoic acid and compound 3 i.e. picric acid both are more acidic than $H_{2}C{O}_3.$
Hence, option (a) is the correct answer.
