Which of the following evolves carbon dioxide when reacted with sodium bicarbonate?
Correct answer: C. CH3CH2COOH
- A. CH3COOCH3
- B. CH3CH2OH
- C. CH3CH2COOH
- D. CH3OOCH3
Explanation
acids are compounds that evolve CO2 when reacted with carbonates and bicarbonatesCarboxylic acids are strong acids and can evolve carbon dioxide with sodium carbonate. 2 CH3-CH2-COOH + Na2CO3 → 2 CH3-CH2-COONa + CO2 + H2O

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
