Some of the Group 2 metal halides are covalent and soluble in organic solvents. Among the following metal halides, the one which is soluble in ethanol is

Options

A. `BeCl_(2)`
B. `MgCl_(2)`
C. `CaCl_(2)`
D. `SrCl_(2)`

Explanation

To solve the question regarding which Group 2 metal halide is soluble in ethanol, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Nature of Ethanol**:
- Ethanol is an organic solvent and is covalent in nature. This is important because it implies that for a substance to be soluble in ethanol, it should also exhibit covalent characteristics.

2. **Understand the Principle of Solubility**:
- The principle "like dissolves like" applies here. This means that covalent compounds tend to dissolve in covalent solvents like ethanol, while ionic compounds generally do not.

3. **Examine Group 2 Metal Halides**:
- The Group 2 metal halides include compounds like BeCl₂, MgCl₂, CaCl₂, SrCl₂, and BaCl₂. We need to determine which of these is covalent.

4. **Analyze Beryllium Chloride (BeCl₂)**:
- Beryllium chloride (BeCl₂) is known to exhibit significant covalent character due to the small size of the beryllium ion (Be²⁺). The small size leads to a high effective nuclear charge, which makes it more likely to share electrons rather than lose them, resulting in covalent bonding.

5. **Conclusion**:
- Since BeCl₂ is covalent and follows the "like dissolves like" principle, it is soluble in ethanol. Therefore, the answer to the question is BeCl₂.

### Final Answer:
The metal halide that is soluble in ethanol is **Beryllium Chloride (BeCl₂)**.
