Question

In carbylamine reaction, primary amine reacts with alkaline $CHC{l}_3$ and the final product is a carbylamine. What is the change in oxidation state of $N$ in carbylamine reaction?

Answer 1

$R-\stackrel{(-3)}{N}{H}_2\underset{KOH}{\overset{CHC{l}_3}{\to }}R-\stackrel{(-3)}{\stackrel{+}{N}}\equiv \stackrel{-}{C}$
Oxidation state of $N$ remains same in both reactant and product.
