The correct order of the basicities of the following compounds is `CH_(3)-underset(2)(CH_(2))-NH_(2)-underset(3)((CH_(3))_(2)-NH,CH_(3)-underset(4)overset(O)overset(||)(C)-NH_(2)`

A

`2gt1gt3gt4`

B

`1gt3gt2gt4`

C

`3gt1gt2gt4`

D

`1gt2gt3gt4`

Text Solution

Verified by Experts

More basic due to presence of two basic poles.
In `CH_(3)CH_(2)NH_(2)` and `(CH_(3))_(2)NH`, order of bassicity (based upon + I effect) of alkyl group, `(CH_(3))_(2)NHgtCH_(3)-CH_(2)NH_(2)` while amides are less basic than amines.
So order of basicity
`gt(CH_(3))_(2)underset(3)(NH)gtCH_(3)-underset(2)(CH_(2)NH_(2)gtunderset(4)(CH_(3)CONH_(2))`
