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 ------------- --

Identify X and Y formed in the following two reactions.

(i) Decan-1-ol $\xrightarrow{\text { Jones reagent }} \mathrm{X}$

(ii). Sodium salt of $\mathrm{X} \xrightarrow{\mathrm{NaOH} / \mathrm{CaO}, \Delta} \mathrm{Y}$

Choose the incorrect statement from the following.

An organic compound $[\mathrm{X}]$ reacts with $\mathrm{H}_2 / \mathrm{Pd}-\mathrm{BaSO}_4$ to give compound $[\mathrm{Y}]$ which reduces Tollen's reagent and undergoes Cannizzaro's reaction. On rigorous oxidation of $[\mathrm{Y}]$ in presence of $\mathrm{KMnO}_4 / \mathrm{H}^{+}$Phthalic acid is the product obtained. What is $[\mathrm{X}]$ ?
