Question
Contrast the reduction of propanamide with $LiAlH_4$ against treating it with Bromine and aqueous $NaOH$ (Hofmann bromamide degradation). What is the major organic product of this specific Hofmann reaction?
Answer: B
💡 Solution & Explanation
The Hofmann bromamide degradation is a classical step-down reaction. The reagent combination ($Br_2/NaOH$) actively excises the carbonyl carbon of the primary amide as a carbonate ion. Thus, the 3-carbon propanamide loses exactly one carbon atom, yielding the 2-carbon ethanamine.
