Question
Which of the following is most basic?
✓

Answer

Benzylamine $\ce{C_6​H_5​CH_2​NH_2}$​ is more basic because benzyl group is electron donating group due to $+I$ effect.
So it is able to increase electron density of $N$ of $\ce{-NH_2}$​ group.
Thus due to higher electron density rate of donation of a free pair of electron is increased I.e basic character is higher While phenyl and nitro group are electron withdrawing group so they are able to decrease the electron density of $N$ of $\ce{−NH_2}$​ group. Hence they are less basic.
