The compound which on reaction with aqueous nitrous acid at low temperature produces an oily nitrosamine is
A.
methylamine
B.
ethylamine
C.
diethylamine
D.
triethylamine
Answer :
diethylamine
Solution :
NOTE : Secondary amines ( aliphatic as well as aromatic ) react with nitrous acid to form N - nitrosoamines.
$${\left( {{C_2}{H_5}} \right)_2}NH + HONO \to $$ $$\mathop {{{\left( {{C_2}{H_5}} \right)}_2}N - N = O + {H_2}O}\limits_{{\text{N - Nitrosodiethylamine}}} $$
