Gammexane is

Options

A. Chlorobenzene
B. DDT
C. Benzene hexa chloride
D. None of these

Answer

**Step-by-Step Solution:**

1. **Identify the Compound**: The question asks about "Gammexane." Gammexane is a chemical compound that is known for its use as an insecticide.

**Hint**: Think about the common uses of chemical compounds in agriculture and pest control.

2. **Chemical Structure**: Gammexane is a derivative of benzene. It specifically has six chlorine atoms attached to a benzene ring. This structure is known as hexachlorobenzene.

**Hint**: Recall that benzene is a six-carbon ring with alternating double bonds, and adding chlorine atoms will create a chlorinated derivative.

3. **Chemical Name**: The systematic name for Gammexane is "Benzene hexachloride" (BHC). This name reflects the structure of the compound, indicating that it is a benzene ring with six chlorine atoms.

**Hint**: Remember that the prefix "hexa-" indicates the presence of six atoms of a particular element in the compound.

4. **Formation Process**: Gammexane is formed through a process called light-induced addition of chlorine to benzene. This reaction typically occurs under specific conditions where light facilitates the addition of chlorine to the benzene ring.

**Hint**: Consider how light can act as a catalyst in chemical reactions, especially in organic chemistry.

5. **Isomerism**: Gammexane exists as an isomer, meaning it can have different structural forms. This is important in understanding its chemical behavior and applications.

**Hint**: Think about how isomers can have different properties even though they have the same molecular formula.

6. **Application**: Gammexane is primarily used as an insecticide, which highlights its role in pest control in agriculture.

**Hint**: Consider the importance of chemical compounds in agriculture and how they help manage pests.

**Final Answer**: Gammexane is benzene hexachloride, a chlorinated compound used as an insecticide.
