Identify the name of the reaction involved in conversion of $A \rightarrow B$ and name the compound $B$.

$$ \mathrm{CH}_3 \mathrm{CN} \xrightarrow[\mathrm{H}_2 \mathrm{O}]{\mathrm{H}^{+}} \mathrm{A}-\xrightarrow[\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}]{\mathrm{Cl}_2 / \text { Red Phosphorous }} \mathrm{B} $$

An organic compound $[\mathrm{X}]$ (Molecular formula $\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_2$ ) reacts with dil. $\mathrm{H}_2 \mathrm{SO}_4$ to form an alcohol [B] and a carboxylic acid [C]. Reaction of compound $[\mathrm{B}]$ with Jones reagent yielded compound $[\mathrm{C}]$. When compound $[\mathrm{C}]$ was heated with $\mathrm{P}_2 \mathrm{O}_5$ an Anhydride was formed. Compound $[\mathrm{X}]$ is ------------- --
