Options

A. Xylene
B. Cyclohexane
C. Benzoic acid
D. Toluene

Explanation

To solve the question regarding the catalytic hydrogenation of benzene, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Reactant**:
- Benzene (C6H6) is an aromatic hydrocarbon known for its stability due to resonance. It has a ring structure with alternating double bonds.

2. **Identify the Reaction Conditions**:
- Catalytic hydrogenation typically involves the addition of hydrogen (H2) in the presence of a catalyst. Common catalysts include nickel (Ni), palladium (Pd), or platinum (Pt).
- The reaction usually requires high temperature and pressure to proceed, as benzene is very stable and does not easily react under normal conditions.

3. **Reaction Process**:
- During catalytic hydrogenation, the hydrogen molecules (H2) will add across the double bonds of benzene.
- The process involves breaking the aromaticity of benzene and converting it into a saturated compound.

4. **Determine the Product**:
- When benzene undergoes catalytic hydrogenation, all the double bonds are hydrogenated. This results in the formation of cyclohexane (C6H12), a saturated cyclic alkane.
- The reaction can be summarized as:
\[ \text{C}_6\text{H}_6 + 3\text{H}_2 \xrightarrow{\text{Ni, high T/P}} \text{C}_6\text{H}_{12} \]

5. **Final Answer**:
- Therefore, the product of the catalytic hydrogenation of benzene is cyclohexane.
