Answer» Correct Answer - B Statement B is incorrect in case of Hofmann bromamide degradation . This is used to synthesis primary amine. In this reaction, amide on reation with `Br_(2)` in an aqueous or ethanolic solution of `NaOH` give `1^(2)` amine with one C atom less than that present in the amide. `RCONH_(2) + Br_(2) + 4KOHoverset(Delta)rarrunderset(1^(@) "amine")(RNH_(2)) + 2KBr +K_(2)CO_(3) + 2H_(2)O` |
