Question

Which of the following is most basic in nature? (A)  NH3  (B)  CH3NH2  (C)  (CH3)2NH  (D)  C6H5N(CH3)2

Basicity of amines depends upon the availability of lone pair of nitrogen for donation. Electron releasing group like -CH3 increases the basicity of amines by increasing electron density over nitrogen, which facilitate the donation of lone pair of electrons. Electron withdrawing groups like -Ph group withdraws electrons and thus, make amines less basic by decreasing electron density over nitrogen. Hence, the order of basic nature of the given amines is (CH3)2NH>C6H5N(CH3)2>CH3NH2>NH3 Thus, (CH3)2NH is most basic.
