Question

Hoffmann's bromamide reaction is used to

• A. prepare tertiary amine
• B. prepare all types of amines
• C. step up the series
• D. step down the series

Answer 1

Answer: (D)

step down the series

Answer 2

Hoffmann bromaraide reaction converts acid amides to primary amines :
\underset{\text{Acid amide}}{{RCONH_{2}}}+Br_{2}+4KOH \to \underset{\text{1^{\circ} amine}}{RNH_{2}}+2KBr+K_{2}CO_{3}+2H_{2}O
The $1^{\circ}$ amine formed has one carbon atom lesser than that present in acid amide
