Identify the product ' Z ' in the following series of reactions. Ethanol

Options

  1. AEthylchloride
  2. BEthyl magnesium chloride
  3. CEthyl amine
  4. DEthane

Correct answer

D. Ethane

Step-by-step solution

Ethanol reacts with thionyl chloride under heat to form ethyl chloride ( CH₃CH₂Cl ) through nucleophilic substitution: CH₃CH₂ OH + SOCl₂ CH₃CH₂Cl + SO₂ + HCl . This alkyl chloride then reacts with magnesium in dry ether to produce the Grignard reagent ethyl magnesium chloride ( CH₃CH₂MgCl ): CH₃CH₂Cl + Mg CH₃CH₂MgCl . When treated with ammonia , the Grignard reagent acts as a strong base, abstracting a proton to yield ethane ( CH₃CH₃ ) and forming magnesium amide chloride : CH₃CH₂MgCl + NH₃ CH₃CH₃ + Mg(Cl)NH₂ .
