Identify the product ' B ' in the following reaction sequence. Alkyl halide Mg Dry ether A NH ₃ ~B

Options

  1. AAlkyl magnesium halide
  2. BAlkyl amine
  3. CHydrocarbon
  4. DAlkyl nitrile

Correct answer

C. Hydrocarbon

Step-by-step solution

Reaction sequence analysis: Alkyl halide R-X reacts with magnesium in dry ether to form Grignard reagent A = R-Mg-X . Grignard reagents are strong bases that react with compounds containing acidic protons. Ammonia NH₃ has acidic hydrogens, producing the corresponding hydrocarbon via proton transfer: R-Mg-X + H-NH₂ R-H + Mg(X)NH₂ . The product B is therefore a hydrocarbon R-H . Among the options, the correct answer corresponds to hydrocarbon: C .
