Ruthenium can form complexes with chloride and water ligands with varying stoichiometers. Three such complexes are: [RuCl2(H2O)4]+ [RuCl3(H2O)3] [RuCl4(H2O)2] a.) What is the oxidation state of ruthenium in each of these complexes? (All have the same oxidation state) b.) All of these complexes are low-spin. How many unpaired electrons are found in each of these complexes? c.)These three complexes appear colored red, yellow, and green (but not necessarily in that order). Match each complex with its apparent color. d.) Could any of these compounds exhibit geometrical isomerism? Show all possible geometric isomers for each of these compounds.
