(b) Hoffmann bromamide REACTION.
(c) `underset("3-Chlorobutanamide")(overset(4)(C)H_(3)-underset(underset(CL)(|))(overset(3)(C)H)-overset(2)(C)H_(2))-overset(1)(C)ONH_(2)overset(Br_(2)//NaOH)(rarr) underset("2-Chloropropanamine")(CH_(3)-underset(underset(Cl)(|))(overset(2)(C)H)-overset(1)(C)H_(2)-NH_(2))`
