MCQ
Amide which gives propanamine by Hoffmann bromamide is:
- ✓Pentanamide
- BHexanamide
- CButanamine
- DPropanamine
✓

Correct option: A.
Pentanamide
In the Hoffmann bromamide reaction, the amine formed has one carbon less than that present in the amide. $\ce{RCONH_2 + Br_2 + 4NaOH} \rightarrow \ce{RNH_2 + Na_2CO_3 + 2NaBr + 2H_2O}$
