What is the spectrochemical series? x = +3, ( iii) [ PtCl4 ] 2- Stereochemistry :-  optically inactive This salt is responsible for giving the Fe2+. The d orbital occupation  : t2g3. Gold is then extracted from this complex using zinc. Electronic configuration: 3d 3 =  t2g3 = 15\sqrt{15}15​≈ 4BM However, if the value of ∆o is greater than the value of pairing energy, the electron enters t2gorbital. NH 3, Cl-, F- etc. In this complex, Cobalt has an oxidation state of +3.
