NCERT Exercise 5.23 - Coordination Compounds
Question: Give the oxidation state, d orbital occupation and coordination number of the central metal ion in the following complexes: (i) K3[Co(C2O4)3] (iii) (NH4)2[CoF4] (ii) cis-[CrCl2(en)2]Cl (iv) [Mn(H2O)6]SO4
Answer: **NCERT answer:** (i) OS = +3, CN = 6, d-orbital occupation is t2g 6 eg 0, (ii) OS = +3, CN = 6, d3 (t2g 3), (iii) OS = +2, CN = 4, d7 ( t2g 5 eg 2), (iv) OS = +2, CN = 6, d5 (t2g 3 eg 2).
