Which of the following compounds form salt with `NaHCO_3`?

Options

A.
B.
C.
D.

Explanation

To determine which compounds form salts with sodium bicarbonate (NaHCO₃), we need to consider the nature of the compounds that can react with NaHCO₃. Sodium bicarbonate is a weak base and can react with acids, particularly carboxylic acids, to form salts, carbon dioxide (CO₂), and water (H₂O).

### Step-by-Step Solution:

1. **Identify the Nature of Sodium Bicarbonate**:
- Sodium bicarbonate (NaHCO₃) is a weak base. It can react with acids to form salts.

2. **Recognize the Type of Compounds that React with NaHCO₃**:
- Sodium bicarbonate primarily reacts with carboxylic acids (RCOOH) because they have a highly acidic hydrogen atom (the hydrogen attached to the carboxyl group).

3. **Write the Reaction**:
- The general reaction between a carboxylic acid (RCOOH) and sodium bicarbonate can be represented as:
\[ RCOOH + NaHCO₃ \rightarrow RCOO^{-}Na^{+} + CO₂ + H₂O \]
- Here, RCOO⁻Na⁺ is the salt formed.

4. **Evaluate the Given Compounds**:
- Check each compound to see if it contains a carboxylic acid functional group (–COOH). If it does, it can react with NaHCO₃ to form a salt.

5. **Conclusion**:
- Only the compounds that contain a carboxylic acid will react with sodium bicarbonate to form a salt. Other functional groups such as alcohols, amines, or esters do not have sufficiently acidic protons to react with NaHCO₃.

### Final Answer:
- The correct compounds that form salts with sodium bicarbonate are those that contain carboxylic acid groups.
