Identify compound Q in following reaction. $\mathrm{R}-\mathrm{OH}+\mathrm{Q} \longrightarrow \mathrm{R}-\mathrm{Cl}+\mathrm{HCl}+\mathrm{POCl}_3$
  1. HCl
  2. $\mathrm{PCl}_3$
  3. $\quad \mathrm{PCl}_5$
  4. $\mathrm{SOCl}_2$

Solution

Alcohols when treated with phosphorous pentachloride yield alkyl halides. $\mathrm{R}-\mathrm{OH}+\mathrm{PCl}_5 \longrightarrow \mathrm{R}-\mathrm{Cl}+\mathrm{POCl}_3+\mathrm{HCl}$
