The correct order of decreasing basicities of $\displaystyle \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2},\left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{2} \mathrm{NH}$ and $\displaystyle \left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{3} \mathrm{~N}$ in aqueous solution is :
Official answer
(D)
$\displaystyle \left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{2} \mathrm{NH}>\left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{3} \mathrm{~N}>\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2}$
