Question

Effect of EDG and EWG group on the basis of strength

Answer 1

Groups with an electron-donor effect(EDG) increase the basicity of the compounds, and groups with an electron-accepting effect(EWG), on the contrary, decrease it.

As an example, in the following series the basicity of amines will increase:

NH3 < NH2CH3 < NH(CH3)2 < N(C2H5)3
