Compounds Containing Nitrogen

The decreasing order of basic nature of the following amines is: Methylamine $>$ Dimethylamine $>$ Trimethylamine $>$ Aniline.

The intermolecular bonding in primary amines is stronger than in secondary amines.

Benzene diazonium chloride when reacted with Aniline in presence of dil. HCl at 273 K yields $\mathrm{C}_6 \mathrm{H}_5-\mathrm{N}=\mathrm{N}-\mathrm{NH}-\mathrm{C}_6 \mathrm{H}_5$

On heating an aliphatic primary amine with $\mathrm{CHCl}_3$ in presence of Ethanolic KOH , a Nitrile is formed
