Indicate which nitrogen compound amongst the following would undergo Hofmann's reaction (i.e. reaction with Br2 and strong KOH) to furnish the primary amine (R - NH2)
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
When an amide is treated with bromine in an aqueous or ethanolic solution of sodium hydroxide, degradation of amide takes place leading to the formation of primary amine. This reaction involves the degradation of amide and is popularly known as Hoffmann bromamide degradation reaction. R - CONH2 + Br2 + 4KOH -> R - NH2 + 2KBr + K2CO3 + 2H2O

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
