Answer» `-NO_(2)` group `-CONH_(2)` group Aromatic `NH_(2)` group Aliphatic `NH_(2)` group. Solution : Hence choice (c ) is correct(a) is incorrect. Aliphatic p-and `s-NO_(2)` groups react with `HNO_(2)` but not with `BETA`-napththol. `-UNDERSET(O)underset(\|\|)C-NH_(2)`group react with `HNO_(2)` and produces `N_(2)` gas and does not react with `beta`-naphthol. Hence choice(b) is incorrect An aliphatic amine reacts with `HNO_(2)` and produces alcohol. Here first an aliphatic diazonium SALT is formed which being unstable immediately reacts with `H_(2)O` to form alcohol. While aromatic amines when they form diazonium salts are highly STABLE and hence can be used to diazonium salts are highly stable and hence can be used to take part in dizonium caupling reactions. Hence choice (d) is incorrect.
