Benzophenone does not react with

Options

A. `RNH_(2)`
B. `SO_(3)`
C. `NaOH`
D. `Na_(2)CO_(3)`

Explanation

**Step-by-Step Solution:**

1. **Identify the Structure of Benzophenone**: Benzophenone is an organic compound with the formula C13H10O. It consists of two phenyl groups (C6H5) attached to a carbonyl group (C=O). Its structure can be represented as:
\[ \text{C}_6\text{H}_5\text{C(=O)C}_6\text{H}_5 \]

2. **Understanding Reactivity**: Benzophenone is a ketone, which means it has a carbonyl group (C=O) flanked by two carbon atoms. Ketones generally undergo certain types of reactions, including nucleophilic additions and reactions with amines.

3. **Reactions with Different Reagents**:
- **Amine Derivatives**: Benzophenone can react with amine derivatives (RNH2) through nucleophilic addition, forming an imine or an amine derivative.
- **Sulfones (SO3)**: It can also react with sulfonyl chlorides or other sulfonating agents.
- **Sodium Hydroxide (NaOH)**: In the presence of NaOH, benzophenone can undergo a Cannizzaro reaction because it lacks alpha-hydrogens. This reaction involves the disproportionation of the ketone to form an alcohol and a carboxylic acid.

4. **Non-Reactivity with Certain Reagents**:
- **Sodium Carbonate (Na2CO3)**: Benzophenone does not react with sodium carbonate. This is because sodium carbonate is a weak base and does not provide the necessary conditions for a reaction with benzophenone.

5. **Conclusion**: Therefore, the statement that "Benzophenone does not react with" can be concluded as:
- Benzophenone does not react with Na2CO3.

**Final Answer**: Benzophenone does not react with sodium carbonate (Na2CO3).
