Arrange the following amines in the decreasing order of their basic strength.
Aniline (I), Benzylamine (II), p- toluidine (III)

A

`I gt II gt III`

B

`III gt II gt I`

C

`II gt I gt III`

D

`II gt III gt I`

Text Solution

Verified by Experts

The correct Answer is:
D
Among the given compounds, benzylamine `(C_6H_5CH_2NH_2)` is the most basic because in it lone pair of nitrogen is not involved. In resonance. It is available for donation p-toludine, due to the presence of electron releasing group `(-CH_3` group) is more basic than aniline but less basic than benzylamine.
hence the order of basic strength is
