Question

The reaction of $SOC{l}_2$ on alcohol to form alkyl chlorides gives good yields because-

• A. Alkyl chlorides are immiscible with $SOC{l}_2$
  
• B. The other products of the reaction are gaseous and escape out.
• C. Alcohol and $SOC{l}_2$ are soluble in water
• D. The reaction occurs via intermediate formation of an alkyl chloro sulphite

Answer 1

The correct option is B The other products of the reaction are gaseous and escape out.

The reaction of $SOC{l}_2$ on alkanols to form alkyl chlorides gives good yields because the other products of the reaction are gaseous and escape out.
$C_2{H}_{5}OH+Cl-SO-Cl\to C_2{H}_{5}Cl+S{O}_2\uparrow +HCl$
It is one of the most important methods of preparing alkyl halides.
