Your EXAM FORM is 1 CHEM 162-2006 FINAL EXAM + ANSWERS CHAPTER 21 – TRANSITION METALS AND COORDINATION COMPOUNDS COORDINATION COMPOUNDS The following two compounds represent which kinds of isomerism? [Co(NH 3 ) 5 SCN]Cl 2 [Co(NH 3 ) 5 NCS]Cl 2 A. cis-trans isomerism B. coordination isomerism C. optical isomerism D. plane-polarized isomerism E . linkage isomerism A. cis-trans isomerism A cis-isomer would have two SCN groups on one side of the transition metal. A trans-isomer would have two SCN groups on opposite sides of the transition metal. This ion doesn’t contain two SCN groups. Therefore it can’t form cis or trans isomers. B. coordination isomerism Coordination isomers would be [MX + ]Y - and [MY + ]X - C. optical isomerism Optical isomers would be mirror images of each other. These aren’t mirror images of each other. D. plane-polarized isomerism
