To correct the order of basic nature is

Options

A. `NH_(3)gtCH_(3)NH_(2)gtC_(6)H_(5)NH_(2)`
B. `C_(6)H_(5)NH_(2)gtNH_(2)gtCH_(3)NH_(2)`
C. `CH_(3)NH_(2)gtNH_(3)gtC_(6)H_(5)NH_(2)`
D. None of these

Answer

C

Explanation

`CH_(3)NH_(2)` is more basic than `NH_(3)` due to presence of electrons donating methyl group.
(ii) `C_(6)H_(5)NH_(2)` is less basic than `NH_(3)` due to presence of electrons donating methyl group.
`therefore` Correct order of basic nature is
`CH_(3)NH_(2)gtNH_(3) gt C_(6)H_(5)NH_(2)`
