(B) The Hofmann bromamide degradation reaction proceeds through the following steps:$1$. Formation of $N$-bromamide: $R-CONH_2 + Br_2 + 2KOH 	o R-CONHBr + KBr + H_2O$$2$. Formation of isocyanate: $R-CONHBr + KOH 	o R-NCO + KBr + H_2O$$3$. Hydrolysis of isocyanate: $R-NCO + 2KOH 	o R-NH_2 + K_2CO_3$In this mechanism,$RCONHBr$ and $R-NCO$ are intermediates. $RCON$ and $RNC$ (isocyanide) are not formed as intermediates.

Which of the following compounds is $NOT$ formed as an intermediate product in the Hofmann bromamide degradation reaction?
