Vedclass · Answer

(C) Compound $(Y)$ gives the iodoform test,which means it contains an acetyl group $(CH_{3}-C=O)$.$PCC$ (Pyridinium chlorochromate) is an oxidizing agent that oxidizes primary alcohols to aldehydes and secondary alcohols to ketones.Since compound $Y$ is formed from $X$ using $PCC$ and $Y$ gives the iodoform test,$Y$ must be acetaldehyde $(CH_{3}CHO)$,as it is the only aldehyde that gives the iodoform test.Therefore,the starting material $X$ must be ethanol $(CH_{3}CH_{2}OH)$.The reactions are as follows:$CH_{3}CH_{2}OH$ $\xrightarrow{PCC} CH_{3}CHO$ $\xrightarrow{I_{2}/OH^{-}} CHI_{3} + HCOONa$

An organic compound $X$ on treatment with $PCC$ in dichloromethane gives the compound $Y$. Compound $Y$ reacts with $I_{2}$ and alkali to form a yellow precipitate of triiodomethane. The compound $X$ is
