Hofmann rearrangement
In the Hofmann rearrangement an unsubstituted amide is treated with sodium hydroxide and bromide to give a primary amine that has one carbon lesser than starting amide.

In the migrating group is chiral then is configuration is retained. Electron releasing effects in the migrating group increases reactivity of Hofmann rearrangement.
Arrange the following amides according to their relative when reacted with `Br_(2)` in excess of strong base :
