NEET levelSingle correct optionDifficulty 1 of 3hx112

Conversion of an alcohol $R - OH$ into $R - Cl$ is best carried out with $SOCl X_{2}$ because

Aboth by-products, $SO X_{2}$ and $HCl$ , escape as gases, so the product is easy to purify
Bthe by-products are $POCl X_{3}$ and $HCl$ , which are easy to separate
Cit converts the $C - C$ bond into $C - Cl$
Dit gives $R - Cl$ with rearrangement of the carbon skeleton

Answer: A

In

R - OH + SOCl X_{2} R - Cl + SO X_{2} + HCl

both by-products are gases and leave the mixture, giving a pure alkyl chloride.

POCl X_{3}

is a liquid that must be separated by distillation, which is the drawback of

PCl X_{5}

.
