324091 In aqueous solution the weakest base is

1 \(\mathrm{CH}_{3} \mathrm{NH}_{2}\)
2 \(\left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH}\)
3 \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2}\)
4 \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NHCH}_{3}\)

324092 The correct order of decreasing basic character is
\(\mathop {{{\rm{C}}_{\rm{6}}}{{\rm{H}}_{\rm{5}}}{\rm{N}}{{\rm{H}}_{\rm{2}}}}\limits_{\rm{I}} \)
\(\mathop {{{\rm{C}}_{\rm{6}}}{{\rm{H}}_{\rm{5}}}{\rm{C}}{{\rm{H}}_{\rm{2}}}{\rm{N}}{{\rm{H}}_{\rm{2}}}}\limits_{{\rm{II}}} \)
