  • \( \text{Phenol} \)
  • \( \text{Benzene} \)
  • \( \text{Ethylbenzene} \)
  • \( \text{Phenyl ether} \)
Show Solution

The Correct Option is B

Solution and Explanation

The reaction occurs in two stages: 1. Chlorobenzene (\( \text{C}_6\text{H}_5\text{Cl} \)) reacts with magnesium in dry ether, yielding phenyl magnesium chloride (\( \text{C}_6\text{H}_5\text{MgCl} \)), a Grignard reagent: \[ \text{C}_6\text{H}_5\text{Cl} + \text{Mg} \xrightarrow{\text{dry ether}} \text{C}_6\text{H}_5\text{MgCl}. \] 2. Phenyl magnesium chloride subsequently reacts with ethanol (\( \text{C}_2\text{H}_5\text{OH} \)), producing benzene (\( \text{C}_6\text{H}_6 \)) and magnesium ethoxide (\( \text{C}_2\text{H}_5\text{OMgCl} \)): \[ \text{C}_6\text{H}_5\text{MgCl} + \text{C}_2\text{H}_5\text{OH} \to \text{C}_6\text{H}_6 + \text{C}_2\text{H}_5\text{OMgCl}. \] Final Answer: \[ \boxed{\text{Benzene}} \]
