The statement correct about X is :

Options

A. It is racemate
B. It is a product of an addition reaction
C. It is formed through a cationic intermediate
D. It is optically active

Answer

To solve the question regarding the reaction of cyclohexene with bromine in the presence of light to form product X (C₆H₉Br), we will analyze the reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactant is cyclohexene (C₆H₁₄), which is an alkene.

2. **Understand the Reaction Conditions**:
- The reaction occurs in the presence of limited bromine and light. The presence of light suggests that a free radical mechanism is involved.

3. **Mechanism of Reaction**:
- The reaction proceeds via a free radical mechanism, which involves the homolytic cleavage of the Br-Br bond due to the energy provided by light. This generates bromine radicals.

4. **Formation of the Free Radical**:
- The bromine radical can then abstract a hydrogen atom from the allylic position of cyclohexene, forming an allylic radical.

5. **Bromination of the Radical**:
- The allylic radical can react with another bromine molecule, leading to the substitution of a bromine atom at the allylic position. This can occur from either the front or the back side of the radical, resulting in two different stereoisomers.

6. **Formation of Product X**:
- The product formed (C₆H₉Br) is a mixture of two stereoisomers due to the two possible approaches of the bromine radical. This mixture is known as a racemic mixture.

7. **Optical Activity**:
- Since the product is a racemic mixture, it is optically inactive because the two enantiomers will cancel each other's optical activity.

8. **Conclusion**:
- The correct statement about product X is that it is a racemic mixture. It is not a product of an addition reaction, it is formed through a cationic intermediate, and it is not optically active.

### Final Answer:
The correct statement about product X (C₆H₉Br) is that it is a racemic mixture.
