The order of basicity among the following compounds is:
II > I > IV > III
I > IV > III > II
IV > II > III > I
IV > I > II > III
→ The conjugate acid is stabilized by resonance with two different −NH2 group.
Arrange the following in the increasing order of their basicity.
CH3NH2(I) ;(CH3)2NH(II) ;C6H5NH2(III) ;(CH3)3N(IV)
