Question

The reaction: ${C2H5OH + SOCl2 ->[{\text{Pyridine}}] C2H5Cl + SO2 + HCl}$ is known as

• A. Kharasch effect
• B. Williamson's synthesis
• C. Darzen's procedure
• D. Hunsdiecker reaction

Answer 1

Answer: (C)

Darzen's procedure

Answer 2

Alkyl halides can be prepared by treating alcohol with ${SOCl_2}$. ${CH_3CH_2OH + SOCl_2 -> CH_3 CH_2 Cl + SO_2 + HCl}$ This reaction is known as Darzen's procedure. Note : ${SOBr_2}$ and ${SOI_2}$ are not used in this reaction because ${SOBr_2}$ is less stable and ${SOI_2}$ does not exist.
