What is the IUPAC name of the product Y in the given reaction sequence? \begin{center} \includegraphics[width=0.5\textwidth]{TSE 153.png} \end{center}

• A. 2,3,4,5,6,7 - hexahydroxyheptanoic acid
• B. 2,3,4,5,6,7 - pentahydroxyhexanoic acid
• C. 3,4,5,6 - trihydroxyheptanoic acid
• D. 3,4,5 - trihydroxyhexanoic acid \vspace{0.5cm}

Hint:

The presence of multiple hydroxyl groups in the product suggests that this is a polyhydroxy carboxylic acid formed from an aldehyde.

Answer 1

The Correct Option is A

The reaction sequence starts with an aldehyde group, which reacts with cyanide to form a cyanohydrin intermediate. Upon hydrolysis, the cyano group is converted into a carboxyl group, resulting in hexahydroxyheptanoic acid as the product Y. \vspace{0.5cm}
