B. Phenol
C. Methyl benzene
D. Benzoic acid

Answer

To solve the problem, we need to analyze the reaction of chlorobenzene with magnesium in dry ether and the subsequent hydrolysis of the resulting compound.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- We start with chlorobenzene (C6H5Cl) and magnesium (Mg) in dry ether.

2. **Formation of Grignard Reagent**:
- When chlorobenzene reacts with magnesium in dry ether, it forms a Grignard reagent. The reaction can be represented as:
\[ \text{C}_6\text{H}_5\text{Cl} + \text{Mg} \xrightarrow{\text{dry ether}} \text{C}_6\text{H}_5\text{MgCl} \]
- Here, the compound formed is C6H5MgCl, which we will refer to as compound X.

3. **Hydrolysis of the Grignard Reagent**:
- The next step is the hydrolysis of the Grignard reagent (C6H5MgCl). Hydrolysis involves the addition of water (H2O) to the Grignard reagent:
\[ \text{C}_6\text{H}_5\text{MgCl} + \text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_5\text{OH} + \text{Mg(OH)Cl} \]
- In this reaction, the Grignard reagent reacts with water to produce phenol (C6H5OH) and magnesium hydroxide chloride (Mg(OH)Cl).

4. **Final Product**:
- The final product obtained after hydrolysis is phenol (C6H5OH).

### Summary of the Reaction:
- The reaction of chlorobenzene with magnesium in dry ether produces the Grignard reagent (C6H5MgCl), which upon hydrolysis yields phenol (C6H5OH).
