1. Explain why bothcisandtransisomers are possible for [Co(NH3)2(C2O4)2]-but only

thecisisomer is possible for [Co(NH3)4(C2O4)]+.

2. Is more than one geometric isomer possible for the complex [Co(NH3)5Cl]2+ion? Why

or why not? If your answer is yes, provide a sketch of both isomers.

3. How many total isomers are possible for the compound [Co(C2O4)2(NH3)Cl]2-? Make

sketches of these isomers. Indicate optical isomers and draw them as mirror images.
