Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Controlled oxidation of toluene gives aldehyde derivative.
Step 1: Reaction.
\[ \text{Toluene} \rightarrow \text{Benzylidene diacetate (X)} \]
Step 2: Hydrolysis.
\[ \text{(X)} \rightarrow \text{Benzaldehyde (Y)} \]
Step 1: Reaction.
\[ \text{Toluene} \rightarrow \text{Benzylidene diacetate (X)} \]
Step 2: Hydrolysis.
\[ \text{(X)} \rightarrow \text{Benzaldehyde (Y)} \]
