Vedclass · Answer

(B) The reaction of alcohols with thionyl chloride $(SOCl_2)$ is represented as: $R-OH + SOCl_2 \rightarrow R-Cl + SO_2(g) + HCl(g)$.In this reaction,the by-products formed are $SO_2$ and $HCl$,both of which are gases.Since these gases escape from the reaction mixture,the equilibrium shifts in the forward direction according to Le Chatelier's principle,resulting in high yields of pure alkyl chlorides.

The reaction of $SOCl_2$ on alkanols to form alkyl chlorides gives good yields because
