The correct answer is:
D. carboxyl group
Explanation:
The carboxyl group (-COOH) reacts with a saturated solution of sodium bicarbonate (NaHCO₃) to produce carbon dioxide (CO₂) gas, which appears as bubbles.
The reaction is as follows:
R-COOH + NaHCO₃ -----> R-COONa + H₂O + CO₂(g) bubbles
Other functional groups like hydroxyl, carboalkoxyl, and carbonyl do not produce CO₂ bubbles with NaHCO₃.
