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 This is a meaningless term. E. linkage isomerism Linkage isomers have the metal ion linked to different sites on the ligand. In this case, the metal ion is linked to the sulfur part of the SCN, in one case, and the nitrogen part of the SCN, in the other case. Hence, this is a linkage isomer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
