Which of the following compounds is expected to be most basic ?
Answer»
Solution :The basicity depends on the avaliablity of lone pair on N. Due to the PRESENCE of electron DONATING `CH_(3)` group the electron density on N increases. In COMPOUNDS (C) and (D) due to the presence of electronegative element (O and Cl respectively), availability of the lone pair on N is involved into RESONANCE with benzene.
