Question

Identify the major product C formed in the following reaction sequence: [Reaction Scheme Missing]

A

Butylamine

B

Butanamide

C

α\alpha-Bromobutanoic acid

D

Propylamine

Step-by-Step Solution

The specific chemical reaction sequence is missing from the provided text. However, in the context of the NEET 2024 exam, this question featured a multi-step sequence culminating in the Hoffmann bromamide degradation reaction. In that specific sequence, butanoic acid is typically converted into butanamide (a 4-carbon amide). When butanamide is treated with Br2Br_2 and an aqueous or ethanolic solution of NaOHNaOH (Hoffmann bromamide degradation), it yields propylamine (CH3CH2CH2NH2CH_3CH_2CH_2NH_2). This reaction is characteristic for producing a primary amine with one carbon atom less than the parent amide.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Amines. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
