Question

The correct product of the following reaction is :

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Oxidation of Alkyl Benzenes: When treated under strong oxidising conditions, benzylic-H systems are oxidised all the way to the carboxylic acid. The alkyl substituent can be methyl-, $1^o$ or $2^o$ alkyl.
$3^o$ alkyl are not oxidised because they lack a benzylic-H (Must have at ​least 1 benzylic hydrogen​.)
