1. (a) Determine the oxidation state and the number of d electrons of the metal centre and predict the geometry of the following metal complexes using the valence bond theory with the aid of the "electron-in-boxes" diagram. Also indicate the atomic orbitals of the central atom that are involved in the hybridization to form hybrid orbitals. [Co(NH3)6]+ (ii) [MnCl4]?- (iii) [Cu(CN)4]3- "- 11-11 (9 marks) (b) Based on the oxidation state and the number of d electrons determined in (a), determine the number of unpaired electrons and the crystal field stabilization energy (CFSE in Dq units) for each of the three different complexes in (a) (i) to (iii) using the crystal field theory (P= pairing energy). Show the electronic configuration of the d electrons in the form of an orbital diagram in each case. Predict also whether the complexes are diamagnetic or paramagnetic in nature. (9 marks)
