(consider complete conversion).

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