Problem

Crystal field theory provides correct electronic distribution of central metal under surrounding ligand field, hence it clearly explains magnetic moment, colour of a complex. Which of the following complex is high spin ? (1) K4[Fe(CN)6]\text{K}_4[\text{Fe}(\text{CN})_6] (2) [PtCl4]2−[\text{PtCl}_4]^{2-} (3) [CoF6]3−[\text{CoF}_6]^{3-} (4) [Ni(NH3)6]2+[\text{Ni}(\text{NH}_3)_6]^{2+}
