Q. What product will form when $ N $ , $ N $ - dimethyl aniline reacts with $ NaNO_2 $ and dilute $ HCl $ at low temperature ?

Solution:

In tertiary aromatic amines, there is no N−H bond. Therefore, nitrosoation on Nitrogen atom and salt formation is not possible, instead the aromatic ring is nitrosoated at the para position forming a p-nitroso derivative. This derivative on reaction with alkali gives parrot green colouration.
