Answer:
Introduction:
Benzoic acid is a carboxylic acid that consists of a benzene ring with a carboxyl group (-COOH) attached to it. It is used in various industries, including food preservation, pharmaceuticals, and perfumes. One of the methods to prepare benzoic acid is through the oxidation of tert-butylbenzene.

Oxidation of tert-Butylbenzene:
The oxidation of tert-butylbenzene involves the conversion of the tert-butyl group (-C(CH3)3) to a carboxyl group (-COOH). This reaction can be achieved by using a strong oxidizing agent, such as potassium permanganate (KMnO4) or potassium dichromate (K2Cr2O7) in the presence of an acid catalyst, such as sulfuric acid (H2SO4).

Reaction Mechanism:
1. The tert-butylbenzene molecule reacts with the oxidizing agent (KMnO4 or K2Cr2O7) and acid catalyst (H2SO4) to form a benzylic carbocation intermediate.
2. The benzylic carbocation intermediate undergoes rearrangement to form the more stable carbocation.
3. The carbocation is then attacked by water (H2O) to form a tert-butyl alcohol intermediate.
4. The tert-butyl alcohol intermediate undergoes further oxidation by the oxidizing agent to form the benzoic acid product.

Explanation of the Correct Answer:
The correct answer is option 'B' - False. Benzoic acid cannot be prepared by the oxidation of tert-butylbenzene. The oxidation of tert-butylbenzene leads to the formation of tert-butyl alcohol, not benzoic acid. This is because the tert-butyl group is oxidized to a carboxyl group, resulting in the formation of tert-butyl alcohol. To obtain benzoic acid, other methods such as the oxidation of toluene or the hydrolysis of benzaldehyde can be employed.

Conclusion:
In summary, benzoic acid cannot be prepared by the oxidation of tert-butylbenzene. The oxidation of tert-butylbenzene leads to the formation of tert-butyl alcohol, not benzoic acid. Other methods, such as the oxidation of toluene or the hydrolysis of benzaldehyde, are used to prepare benzoic acid.
