Gammaexane is

Options

A. Bromobenzene
B. Benzylchloride
C. Chlorobenzene
D. Benzene hexachloride

Answer

To determine which compound is referred to as gamma hexane, we need to analyze the options provided and identify the structure of gamma hexane.

### Step-by-Step Solution:

1. **Understanding Gamma Hexane**:
Gamma hexane is a chemical compound that is specifically known as Benzene Hexachloride (BHC). It is derived from benzene and has six chlorine atoms attached to the benzene ring.

2. **Analyzing the Options**:
- **Option A: Bromobenzene** - This compound has a bromine atom attached to a benzene ring. It does not match the structure of gamma hexane.
- **Option B: Benzyl Chloride** - This compound has a chlorine atom attached to a benzyl group (which is a phenyl group attached to a CH2 group). It does not match the structure of gamma hexane.
- **Option C: Chlorobenzene** - This compound has a chlorine atom directly attached to a benzene ring. It does not match the structure of gamma hexane.
- **Option D: Benzene Hexachloride** - This compound has six chlorine atoms attached to the benzene ring, which matches the definition of gamma hexane.

3. **Identifying the Correct Answer**:
Since Benzene Hexachloride (BHC) is the compound that corresponds to gamma hexane, we conclude that the correct answer is **Option D**.

### Final Answer:
**Gamma hexane is Benzene Hexachloride (BHC), which corresponds to Option D.**
