Number of amine compounds from the following giving solids which are soluble in $$\mathrm{NaOH}$$ upon reaction with Hinsberg's reagent is _________.

An amine $$(\mathrm{X})$$ is prepared by ammonolysis of benzyl chloride. On adding p-toluenesulphonyl chloride to it the solution remains clear. Molar mass of the amine $$(\mathrm{X})$$ formed is _________ $$\mathrm{g} \mathrm{mol}^{-1}$$.

(Given molar mass in $$\mathrm{gmol}^{-1} \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16, \mathrm{~N}: 14$$)

$$9.3 \mathrm{~g}$$ of pure aniline upon diazotisation followed by coupling with phenol gives an orange dye. The mass of orange dye produced (assume 100% yield/conversion) is ________ g. (nearest integer)

$$\mathrm{X} \mathrm{~g}$$ of ethanamine was subjected to reaction with $$\mathrm{NaNO}_2 / \mathrm{HCl}$$ followed by hydrolysis to liberate $$\mathrm{N}_2$$ and $$\mathrm{HCl}$$. The $$\mathrm{HCl}$$ generated was completely neutralised by 0.2 moles of $$\mathrm{NaOH} . \mathrm{X}$$ is _________ g.
