What are X and Y in the following set of reactions?
What are X and Y in the following set of reactions?
Show Hint
$KMnO_{4}$ converts alkyl groups on benzene rings to carboxylic acids.

Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
This concerns the electrophilic substitution on toluene and its subsequent side-chain oxidation to carboxylic acid.
Step 2: Meaning
Bromination of toluene gives bromo-toluene, and $KMnO_{4}$ oxidation of the methyl group yields the benzoic acid derivative.
Step 3: Analysis
The sequence of reagents determines the final substitution pattern. Option A corresponds to the expected product path.
Step 4: Conclusion
Structure 1 provides the correct product arrangement.
Final Answer: (A)
