In which of the following metal to metal bond is present ?

Options

A. Cupric chloride
B. Stannous chloride
C. Mercurous chloride
D. Mercutic chloride

Explanation

To determine in which of the given compounds a metal-to-metal bond is present, we will analyze the structures and bonding of the compounds mentioned.

### Step-by-Step Solution:

1. **Identify the Compounds**: The compounds mentioned are:
- Cupric Chloride (CuCl2)
- Stannous Chloride (SnCl2)
- Mercurous Chloride (Hg2Cl2)
- Mercuric Chloride (HgCl2)

2. **Analyze the Bonding in Each Compound**:
- **Cupric Chloride (CuCl2)**: This compound consists of copper (Cu) and chlorine (Cl). In CuCl2, copper forms ionic bonds with chlorine, and there is no metal-to-metal bond present.

- **Stannous Chloride (SnCl2)**: This compound consists of tin (Sn) and chlorine (Cl). Similar to CuCl2, SnCl2 has ionic bonding between tin and chlorine, and there is no metal-to-metal bond present.

- **Mercurous Chloride (Hg2Cl2)**: This compound consists of two mercury (Hg) atoms and two chlorine (Cl) atoms. In this compound, the two mercury atoms are bonded together, creating a metal-to-metal bond. The bonding is characterized by the presence of a diatomic ion (Hg2) which indicates a metal-metal interaction.

- **Mercuric Chloride (HgCl2)**: This compound consists of mercury (Hg) and chlorine (Cl). In HgCl2, mercury forms ionic bonds with chlorine, and there is no metal-to-metal bond present.

3. **Conclusion**: After analyzing the bonding in each compound, we find that the only compound with a metal-to-metal bond is **Mercurous Chloride (Hg2Cl2)**.

### Final Answer:
The metal-to-metal bond is present in **Mercurous Chloride (Hg2Cl2)**.
