Diethyl amine is an example for
1 \(1^{\circ}\) amine
2 \(3^{\circ}\) amine
3 \(2^{\circ}\) amine
4 quaternary ammonium salt
Explanation:
The lone pair of electrons present on nitrogen atom of benzylamine are not involved in it is strongest base among the given amines.

The correct order of the increasing basicity of methyl amine, ammonia and aniline is
1 methyl amine \( < \) aniline \( < \) ammonia
2 aniline \( < \) ammonia \( < \) methyl amine
3 aniline \( < \) methyl amine \( < \) ammonia
4 ammonia \( < \) aniline \( < \) methyl amine
Explanation:
In aniline the lone pair on N is involved in delocalization with benzene ring and is not available for protonation. Methyl amine is a stronger base than ammonia because + I effect of methyl group increases electron density on N making it more basic than \({\rm{N}}{{\rm{H}}_{\rm{3}}}\). Cannot be protonated. least basic
