Question

The correct order of basicities of the following compounds is

                        CH3CH2NH2        (CH3)2NH     CH3CONH2

          (1)                                         (2)                       (3)                  (4)

Solution

Correct option is

1 > 3 > 2 > 4

I is most due to formation of resonance stablised conjugate acid   

IV is amide, least basic

Also, among alkyl amines, 2o is more basic than 1o amine. Hence, overall order of basic strength is  

              1 > 3 > 2 > 4.
