Q.
Nitrosoamines ($R_{2}N - N = O$) are soluable in water. On heating them with conc $H_{2}SO_{4}$, they give secondary amines. The reaction is called
A) Perkin’s reaction
B) Fries reaction
C) Liebermann nitroso reaction
D) Etard reaction
Explanation
(c)
Nitrosoamine on heating with conc.$H_{2}SO_{4}$ gives secondary amine. This reaction is called Liebermann nitroso reaction.
$R_{2}N - N = O + H_{2}O\overset{Conc.H_{2}SO_{4}}{\rightarrow}R_{2}NH + HNO_{2}$
nitrosoamine secondary
amine
