Chlorobenzene reacts with Mg in dry ether to give a compound A, which further reacts with ethanol to give B. Identify B.

Options

  1. APhenol
  2. BBenzene
  3. CEthyl benzene
  4. DPhenyl ether

Correct answer

B. Benzene

Step-by-step solution

Chlorobenzene reacts with magnesium in the presence of dry ether to form phenylmagnesium chloride, which is a Grignard reagent. This is compound A. C₆H₅Cl + Mg dry ether C₆H₅MgCl Grignard reagents are highly reactive towards compounds containing active or acidic hydrogen atoms. Ethanol contains an acidic hydrogen atom attached to the oxygen atom. When phenylmagnesium chloride reacts with ethanol, it abstracts the acidic proton to form benzene. This is compound B. C₆H₅MgCl + C₂H₅OH C₆H₆ + Mg(OC₂H₅)Cl Thus, the final
