Hint: Any aliphatic carbon with hydrogen attached to it, in combination with a benzene ring will be oxidized to benzoic acid regardless of the length of the entire side chain as is a strong oxidizing agent.
Complete step by step answer:
Here, we are provided with ethyl benzene i.e. that has to be oxidized with . is a strong oxidizing reagent. What it does is it will oxidize the carbon that is attached to the benzene ring because the hydrogen attached to that carbon will be the most acidic hydrogen. The two hydrogens attached to the carbon get replaced by two groups. Similarly, in the place of an group will get attached. As a result, three groups will get attached to the benzene ring. The attachment of three groups will make the product highly unstable due to which it will tend to lose water and the reaction will end with the formation of benzoic acid as an end product.
The reaction is as follows:
Another example can be:
In this example, the result of oxidation of methyl benzene with is benzoic acid.
From the above two cases, we infer that the reaction does not depend on the length of the side chain attached to the benzene ring. Irrespective of the side chain, the will always oxidize it to benzoic acid.
Hence option (C) is correct.
Note:
Keep in mind the trick that no matter how long the side chain is, the result of this reaction will always be benzoic acid as explained above that the reaction does not depend on the length of the side chain attached to the ring.
