Arrange the following in increasing order of their basic strength:

C2H5NH2, (C2H5)2NH, (C2H5)3N, C6H5NH2


By taking into consideration –R effect and steric hindrance of groups we can arrange them in the order C6H5NH2< C2H5NH2<(C2H5)3N<(C2H5)2NH. Because (C2H5)3N has a lot of steric hindrances that reduces the basic strength.
