Indicate which nitrogen compound amongst the following would undergo Hofmann's reaction (i.e., reaction with `Br_2` and strong `KOH`) to furnish the primary amine `(R-NH_2)`

Options

A. `R- overset(overset(O)(||))(C)- NH.CH_(3)`
B. `R- overset(overset(O)(||))(C)- O.NH_(4)`
C. `R- overset(overset(O)(||))(C)- NH_(2)`
D. `R- overset(overset(O)(||))(C) - NHOH`

Answer

C

Explanation

Hoffmann degradation of amide `R- CONH_(2) +Br_(2) + 34KOH rarr underset("Primary amine")(R- NH_(2)) + 2KBr + K_(2)CO_(3) + 2H_(2)O`
