Vedclass · Answer

(C) The given reactions represent the preparation of haloalkanes from alcohols using phosphorus halides.$1$. The reaction of alcohol with phosphorus trichloride is:$3 ROH + PCl_3 \rightarrow 3 RCl + H_3 PO_3$ $(A)$$2$. The reaction of alcohol with phosphorus pentachloride is:$ROH + PCl_5 \rightarrow RCl + HCl + POCl_3$ $(B)$Thus,$A$ is $H_3 PO_3$ and $B$ is $POCl_3$.

The products $A$ and $B$ obtained in the following reactions,respectively,are
$3 ROH + PCl_3 \rightarrow 3 RCl + A$
$ROH + PCl_5 \rightarrow RCl + HCl + B$
