Gammaxene is …………. Isomer of benzene hexa chloride

Options

A. `alpha`
B. `beta`
C. `gamma`
D. `delta`

Explanation

To determine which isomer of benzene hexachloride Gammaxene is, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Benzene Hexachloride (BHC)**:
- Benzene hexachloride is a chemical compound with the molecular formula C6H6Cl6. It is also known as Lindane or hexachlorocyclohexane.

2. **Identifying Isomers**:
- Benzene hexachloride has several isomers due to the different ways chlorine atoms can be attached to the benzene ring. The main isomers are alpha (α), beta (β), and gamma (γ).

3. **Recognizing Gammaxene**:
- Gammaxene specifically refers to the gamma (γ) isomer of benzene hexachloride. This isomer is characterized by the specific arrangement of chlorine atoms on the benzene ring.

4. **Preparation of Benzene Hexachloride**:
- Benzene hexachloride is prepared by the photochlorination of benzene in the presence of chlorine (Cl2) and a substitution catalyst. This process leads to the formation of various isomers, including the gamma isomer.

5. **Separation of Isomers**:
- In the preparation process, the reaction mixture can be treated with solvents like acetic acid and methanol, which dissolve the alpha and beta isomers, leaving behind the gamma isomer.

6. **Conclusion**:
- Therefore, Gammaxene is identified as the gamma (γ) isomer of benzene hexachloride.

### Final Answer:
Gammaxene is the gamma (γ) isomer of benzene hexachloride.
