Options

  1. AKharasch effect
  2. BWilliamson's synthesis
  3. CDarzen's procedure
  4. DHunsdiecker reaction.

Correct answer

C. Darzen's procedure

Step-by-step solution

Darzen's method : Alkyl halides are prepared when thionyl chloride and alcohols are refulxed in presence of pyridine. R- OH + SOCl ₂ reflux Py R- Cl + SO ₂+ HCl . Byproducts of this reaction are gases ( SO ₂, HCl ) so can be easily removed from the reaction mixture.
