Which of the following compound is not a suitable solvent for Grignard reaction ?

Options

A.
B.
C. `CH_(3)-O-CH_(2)-CH_(2)-O-CH_(3)`
D.

Explanation

To determine which of the given compounds is not a suitable solvent for Grignard reactions, we need to analyze the properties of the solvents in question. Grignard reagents are highly reactive and are typically prepared in a polar solvent. Let's go through the steps to identify the unsuitable solvent.

### Step-by-Step Solution:

1. **Understand the Requirements for Grignard Reactions**:
- Grignard reactions require solvents that are polar in nature. This is because polar solvents stabilize the Grignard reagents and facilitate the reaction process.

2. **Identify the Solvents**:
- The question likely provides a list of solvents. Common solvents for Grignard reactions include ethers (like diethyl ether) and other polar solvents. Non-polar solvents, such as hydrocarbons, are not suitable.

3. **Analyze Each Compound**:
- **Ethers (e.g., Diethyl Ether)**: These are polar solvents and are suitable for Grignard reactions.
- **Alcohols**: These are also polar but can react with Grignard reagents, thus not suitable as solvents.
- **Cyclic Ethers**: These are polar and can be suitable as solvents.
- **Cyclohexane**: This is a non-polar solvent and does not stabilize Grignard reagents.

4. **Conclusion**:
- Among the given options, cyclohexane is the compound that is not a suitable solvent for Grignard reactions because it is non-polar.

### Final Answer:
Cyclohexane is not a suitable solvent for Grignard reactions.
