RE-NEET 2026 Chemistry Preparation of Amines Multiple Correct Question

The correct answer is A, as reactions A and D yield aniline as the major product.

In reaction A, the nitrile group ($-CN$) is reduced by lithium aluminum hydride ($LiAlH_4$) to form aniline. In reaction D, the amide ($-CONH_2$) is hydrolyzed under acidic conditions ($HCl, H_2O$) to also produce aniline.

Option B involves a reaction that does not lead to aniline, as the product is a different amine. Option C, using sodium borohydride ($NaBH_4$), reduces the nitro group but does not yield aniline directly. Thus, these options fail to produce aniline as the major product.
