B. `Cl_(2)`
C. Both (1) and (2) (4
D. None of these

Answer

To solve the question regarding the preparation of chloroform (CHCl3) from ethanol (C2H5OH) and bleaching powder (Ca(OCl)2), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are ethanol (C2H5OH) and bleaching powder (Ca(OCl)2).

2. **Understand the Role of Bleaching Powder**:
- Bleaching powder acts as a chlorinating agent. It is also known for its oxidizing properties and can hydrolyze in the presence of water.

3. **Hydrolysis of Bleaching Powder**:
- When bleaching powder is mixed with water, it undergoes hydrolysis:
\[ \text{Ca(OCl)2} + \text{H2O} \rightarrow \text{Ca(OH)2} + \text{Cl2} \]
- This reaction produces calcium hydroxide (Ca(OH)2) and chlorine gas (Cl2).

4. **Chlorination of Ethanol**:
- The chlorine gas (Cl2) produced in the previous step can react with ethanol. The chlorination of ethanol leads to the formation of chloroform (CHCl3) through a series of reactions:
\[ \text{C2H5OH} + \text{Cl2} \rightarrow \text{CHCl3} + \text{other products} \]
- In this reaction, ethanol is chlorinated to form chloroform.

5. **Final Products**:
- Therefore, the bleaching powder provides both calcium hydroxide (Ca(OH)2) and chlorine gas (Cl2) in the reaction.

### Conclusion:
In the preparation of CHCl3 from ethanol and bleaching powder, the latter provides calcium hydroxide (Ca(OH)2) and chlorine gas (Cl2).
