Here the correct order of basic nature is as follows
${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{–}\text{NH}\text{–}{\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{>}{\text{CH}}_{\text{3}}\text{–}{\text{CH}}_{\text{2}}\text{–}{\text{NH}}_{\text{2}}\text{>}{\text{CH}}_{\text{3}}\text{–}\text{CH}\text{=}\text{NH}\text{>}{\text{CH}}_{\text{3}}\text{–}\text{C}\equiv \text{N}$
$\left(\mathrm{i}\right)$Secondary amine is more basic than primary amine.
$\left(\mathrm{i}\mathrm{i}\right)$$\mathrm{C}{\mathrm{H}}_3–\mathrm{C}\mathrm{H}=\underset{\mathrm{s}{\mathrm{p}}^2}{\mathrm{N}}\mathrm{H}$
$\left(\text{iii}\right){\text{CH}}_{\text{3}}-\text{C¹}\equiv \underset{\text{sp}}{\text{N}}$
