Consider the two complex ions [Cu(CO)4]²+ and [CuCl]²¯. Choose the statements below that are true about this pair of complex ions. Choose all that apply. For [CuCl4]²- there is one unpaired electron. [Cu(CO)4]²+ absorbs light at a shorter wavelength than [CuCl4]²-. For [Cu(CO)4]²+ there are five unpaired electrons. [Cu(CO)4]²+ is high spin because carbon monoxide (CO) is a weak field ligand. [CuCl₂]² is high spin because chloride (CI) is a weak field ligand.
