NEET2002ChemistryHaloalkanes and HaloarenesActual
The reaction: C ₂ H ₅ OH + SOCl ₂ Pyridine C ₂ H ₅ Cl + SO ₂+ HCl is known as
Options
- AKharasch effect
- BWilliamson's synthesis
- CDarzen's procedure
- 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.
