The best solvent to remove butter stain from cloth is :

Options

A. `CHCl_(3)`
B. `C_(2)H_(5)OH`
C. `C_(2)H_(5)OC_(2)H_(5)`
D. `H_(2)O`

Answer

To determine the best solvent for removing a butter stain from cloth, we need to analyze the properties of butter and the solvents provided in the options.

### Step-by-Step Solution:

1. **Identify the Nature of Butter**:
- Butter is primarily composed of fats and oils, which are non-polar substances. Non-polar substances do not dissolve well in polar solvents.

2. **Analyze the Given Solvents**:
- The options provided are:
- CHCl3 (Chloroform)
- C2H5OH (Ethanol)
- C2H5O (Ethyl oxide)
- C2H5 (Ethane)
- H2O (Water)

3. **Classify the Solvents**:
- **CHCl3 (Chloroform)**: This is a non-polar solvent.
- **C2H5OH (Ethanol)**: This is a polar solvent due to the hydroxyl (-OH) group.
- **C2H5O (Ethyl oxide)**: This is also polar.
- **C2H5 (Ethane)**: This is a non-polar solvent.
- **H2O (Water)**: This is a highly polar solvent.

4. **Determine the Best Solvent**:
- Since butter is a non-polar substance, it will dissolve best in a non-polar solvent. Among the options, CHCl3 (Chloroform) is the most effective non-polar solvent for dissolving butter stains.
- Although ethane (C2H5) is also non-polar, chloroform is more effective due to its ability to interact with the non-polar molecules in butter.

5. **Conclusion**:
- Therefore, the best solvent to remove butter stain from cloth is **CHCl3 (Chloroform)**.

### Final Answer:
**The best solvent to remove butter stain from cloth is CHCl3 (Chloroform).**
