Which of the following compounds reacts with $\mathrm{NaHCO}_{3}$ giving $\mathrm{CO}_{2}$ ?
a) $\square$
b)
c) $\mathrm{CH}_{3} \mathrm{CCOOH}$
d)
Solution
Solution Steps
Step 1: Identify the compounds
Compound a) is oxalic acid (HOOC-COOH).
Compound b) is salicylic acid (2-hydroxybenzoic acid).
Compound c) is acetic acid (CH3COOH).
Compound d) is 2,4-dinitroaniline.
Step 2: Determine the reaction with NaHCO₃
Sodium bicarbonate (NaHCO₃) reacts with acids to produce carbon dioxide (CO₂), water, and a salt.
The general reaction is: Acid + NaHCO₃ → Salt + CO₂ + H₂O.
Step 3: Identify which compounds are acids
Oxalic acid (a) is a dicarboxylic acid.
Salicylic acid (b) is a carboxylic acid with a phenol group.
Acetic acid (c) is a carboxylic acid.
2,4-Dinitroaniline (d) is an amine with nitro groups, not an acid.
Final Answer
Compounds a), b), and c) will react with NaHCO₃ to give CO₂.
