Text Solution

Verified by Experts

The correct Answer is:
B
Dye test is given by aromatic primary amines and not by aliphatic amines. Aniline gives diazonium chloride with `HNO_(2)(NaNO_(2)//HCl)` at `0^(@)C` which form coloured dye with phenols. This is dye-tesopt. Aliphatic amines form alcohol with evolution of `N_(2)` on treating with `HNO_(2)`
