Question

The reagent required to convert acetamide into methyl amine is:

A

NaOH/Br2NaOH/Br_2

B

Sodalime

C

Hot conc. H2SO4H_2SO_4

D

PCl5PCl_5

Step-by-Step Solution

The conversion of acetamide (CH3CONH2CH_3CONH_2) to methylamine (CH3NH2CH_3NH_2) involves the loss of one carbon atom (the carbonyl carbon). This transformation is achieved via the Hoffmann bromamide degradation reaction. The reagents used for this reaction are bromine (Br2Br_2) in an aqueous or ethanolic solution of sodium hydroxide (NaOHNaOH) or potassium hydroxide (KOHKOH).

The overall chemical equation is: CH3CONH2+Br2+4NaOH→CH3NH2+Na2CO3+2NaBr+2H2OCH_3CONH_2 + Br_2 + 4NaOH \rightarrow CH_3NH_2 + Na_2CO_3 + 2NaBr + 2H_2O

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.
