Which of the following will not react with Na metal?

Options

A.
B.
C.
D.

Explanation

To determine which of the given compounds will not react with sodium metal, we need to analyze the acidic character of each compound. Sodium metal reacts with compounds that have acidic protons, leading to the formation of sodium salts and the release of hydrogen gas.

### Step-by-Step Solution:

1. **Identify the Compounds**: Let's denote the compounds as A, B, C, and D. We need to analyze each compound's ability to lose a proton (H⁺) and thus determine its acidic character.

2. **Analyze Compound A**:
- Compound A is likely an alcohol or a phenolic compound.
- Alcohols have an acidic hydrogen that can react with sodium to form an alkoxide (R-O⁻Na⁺) and release hydrogen gas (H₂).
- **Conclusion**: Compound A will react with sodium.

3. **Analyze Compound B**:
- Compound B is likely an aromatic compound with acidic protons.
- Similar to Compound A, it can lose protons to form a stable aromatic anion, thus exhibiting acidic behavior.
- **Conclusion**: Compound B will react with sodium.

4. **Analyze Compound C**:
- Compound C is identified as an anti-aromatic compound.
- Anti-aromatic compounds are destabilized by the presence of certain pi electrons, leading to a lack of acidic character.
- Since it does not want to lose protons due to destabilization, it will not react with sodium.
- **Conclusion**: Compound C will NOT react with sodium.

5. **Analyze Compound D**:
- Compound D is phenol, which is known to be acidic.
- It can lose a proton to form a phenoxide ion (C₆H₅O⁻), which is stabilized by resonance.
- **Conclusion**: Compound D will react with sodium.

### Final Conclusion:
Among the compounds A, B, C, and D, **Compound C** will not react with sodium metal due to its anti-aromatic nature, which prevents it from losing protons.
