Options

A. It is obtained by treating westron with `Ca(OH)_(2)`
B. It is used as a solvent.
C. It is used in refrigerators
D. None of the above

Answer

To analyze the compound CCl₂=CHCl, known as Vestrosol, we will evaluate the statements regarding its properties and uses.

### Step-by-Step Solution:

1. **Identify the Compound**:
The compound in question is CCl₂=CHCl, which is known as Vestrosol. This compound contains a double bond between two carbon atoms, with two chlorine atoms attached to one carbon and one chlorine atom attached to the other.

**Hint**: Look at the structure of the compound to understand its functional groups and bonding.

2. **Evaluate Statement A**:
The first statement claims that Vestrosol is obtained by treating Vestron with COH (which likely refers to a chemical reaction involving a reagent). Vestron is represented as CCl₂CHCl₂. When Vestron reacts with COH, it can lead to the formation of Vestrosol.

**Hint**: Consider the reaction mechanism and products formed when Vestron undergoes a reaction with COH.

3. **Check the Reaction**:
The reaction of Vestron (CCl₂CHCl₂) with COH can yield CCl₂=CHCl (Vestrosol) through elimination reactions. This confirms that the first statement is correct.

**Hint**: Review elimination reactions to understand how double bonds are formed in organic compounds.

4. **Evaluate Statement B**:
The second statement mentions that Vestrosol is used as a solvent. This is true; Vestrosol is utilized in various chemical processes as a solvent due to its properties.

**Hint**: Research the applications of Vestrosol to confirm its use as a solvent.

5. **Evaluate Statement C**:
The third statement states that Vestrosol is used in refrigerators. This statement is incorrect. Vestrosol is not typically used as a refrigerant in refrigeration systems.

**Hint**: Investigate the properties of Vestrosol to determine its suitability for refrigeration applications.

6. **Evaluate Statement D**:
The fourth statement is also likely incorrect, as it may pertain to a specific application or property that does not align with the known uses of Vestrosol.

**Hint**: Compare the properties of Vestrosol with those of common refrigerants to understand the differences.

### Conclusion:
Based on the evaluations:
- Statements A and B are correct.
- Statements C and D are incorrect.

Thus, the correct options regarding the compound Vestrosol are A and B.
