The major product in the following reaction is:
Basicity of Aromatic Amines -
The unshared pair of electrons at the nitrogen atom is in resonance with the benzene ring and hence not fully available for donation as in the case of aniline.
-
Nature of group and basicity -
Electron withdrawing groups ( -I and -M effect ) decreases basicity, whereas Electron releasing groups ( +I and +M effect ) increases basicity.
-
1,3,7 Nitrogen have localised lone pair
They have delocalised lone pair so, they are less nucleophilic and less basic
1&3 Nitrogen is mare Nucleophilic and more basic as compared to Nitrogen
Moreover, 3-Nitrogen is most Nucleophilic because of less crowding
More because of less crowding
density more at 1,3
But 3rd N is most
