WebX = Number of electrons lost during the formation of the metal ion from its atom. Y = Number of electrons donated by the ligands. EAN=Z−X+Y. EAN=28−2+8=34. To achieve EAN of 36, [Ni(DMG) 2], needs two electrons. However there are few exceptions from EAN rule. hence, [Ni(DMG) 2] does not act as oxidizing agent. Thus option A is incorrect. Web1.
