Question

Hofmann degradation of benzamide gives aniline. Hofmann bromamide degradation reaction can be used for descending amine series.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

Hoffmann Bromamide reaction is a method of preparing primary amines. Reagent: Amide reaction with bromine and NaOH. $R- \overset{\underset{||}{O}}{C}-NH _{2}+ Br _{2} +4 NaOH \rightarrow R - NH _{2}+ Na _{2} CO _{3}+2 NaBr +2 H _{2} O$ The amine formed has one carbor less than the parent amide.
