Complex ions form when ligands bond to central metal cations. When the central metal cation is a transition metal, the ligands can cause splitting of the metal cation's d-sublevel. This tends to lead to the solution being colored.Answer and Explanation: ...
Anhydrous FeCl3(38 mg, 0.24 mmol) was slowly added to a solution ofM2(100 mg, 0.096 mmol) in 2.5 ml of anhydrous chlorobenzene under nitrogen gas atmosphere. The reaction mixture was stirred at 80 °C for 3 days. After the polymerization, the reaction mixture was precipitat...
