Carboxylic acids reacts with sodium carbonate, gas evolved in this reaction
Correct answer: C. CO2
- A. CO
- B. H2
- C. CO2
- D. Both a & b
Explanation
For example take ethanoic acid as a carboxylic acid = CH3COOH reaction: 2CH3COOH (aq) + Na2CO3 (s) ---> 2CH3COONa (aq) + H2O (l)+ CO2 (g) CO2 gas is evovled.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
