7. Rank the following ligands from strongest to weakest metal-ligand bond strength. | F, CH,CO2, NHẠC,H,NH, CÓ 8. In many cases, a transition metal ion is colored because the metal ion has an electron residing in a d-orbital that absorbs energy and is promoted to a higher energy d-orbital. The energy difference between the d-orbitals depends on the metal ion and the ligand. The complexes Co(NH3)2+ and Co(H20) 2+ are colored, one is red and one is yellow. Predict which...
