Question

gands arge Ka[Fe(C2O4)a] (hint: bidentate oxalate ligands) valence electrons on Metal Charge on the ligands: Charge on the Metal: Revised Count on the Metal (accounting for charge Number of electrons donated from the ligands: Total electrons in this complex: INi(en)2(CI)2] Valence electrons on Metal; Charge on the ligands: Charge on the Metal: Revised Count on the Metal (accounting for charge Number of electrons donated from the ligands Total electrons in this complex: Re(CO)s(PF3)]Cl Valence electrons on Metal: Charge on the ligands: Charge on the Metal: Revised Count on the Metal (accounting for charge) Number of electrons donated from the ligands: Total electrons in this complex: 338

Answer 1

Kg [Fe (4204)3] | Valence electron en metal : 8 ceremony to think (4623015) Charge on the ligands : 2 Charge of the metal : +3 Revised count on the metal : 8+3 = 5€ number of electron donated from ligands: 3x (204 3x. 4 = 12.6 Total election in this complex = 12 + 5 = 17 e [Ni(en)2(CI)2) Valence, e on metal = lo e- (452308) Charge of the ligand : en so, a - - 1 Charge on metal : +2 Revised count on the metal - 10-2 : 8 e- Number of electron donated from the ligand : 2xen + 2 x 4 2x4 2*2 12€ Total election in this complex = 12 + 8 = 20 € Recco)s(PF3) CA Valence er on metal te Charge on the ligands: Coto PF ₂ - 0 Charge on the metal l Revised count on the metal be no. of e donated from ligand = 5x co + 1x PFz ? 5 X 2 + 1*2 Total é in this complex : 12 + 6 = 18 e
