Which one of the following is most soluble in ether

Options

A. `BeCl_(2)`
B. `CaCl_(2)`
C. `SrCl_(2)`
D. None of these

Explanation

To determine which compound is most soluble in ether, we need to analyze the nature of the compounds provided in the options. Ether is an organic solvent, and typically, non-polar or covalent compounds are more soluble in organic solvents like ether.

### Step-by-Step Solution:

1. **Identify the Nature of Ether:**
- Ether is a non-polar organic solvent. Non-polar solvents tend to dissolve non-polar substances better than polar substances.

2. **Analyze the Given Compounds:**
- The options provided are:
- A) BeCl2 (Beryllium chloride)
- B) CaCl2 (Calcium chloride)
- C) SrCl2 (Strontium chloride)
- D) (Another compound not specified in the transcript)

3. **Determine the Polarity of Each Compound:**
- BeCl2 is known to have a covalent character due to the small size and high charge density of the beryllium ion.
- CaCl2 and SrCl2 are ionic compounds and are more polar due to the larger size of calcium and strontium ions, which leads to a greater ionic character.

4. **Compare Solubility in Ether:**
- Since ether is a non-polar solvent, it will favor the solubility of covalent compounds over ionic compounds.
- Among the options, BeCl2 is the most covalent in nature, making it more soluble in ether compared to the ionic compounds CaCl2 and SrCl2.

5. **Conclusion:**
- Therefore, the compound that is most soluble in ether is BeCl2.

### Final Answer:
- **The most soluble compound in ether is BeCl2 (Option A).**
