Question

Semester 2, 2015 CHEM1020 Introductory Chemistry Question 64 [2 marks] Coordination complexes sometimes have several stereoisomers (a) Sketch the fac isomer of the six-coordinate, octahedral complex (CO(NH3)33l which has three ammine ligands and three chloride ligands bound to the central Coll) ion. You do not need to draw the complete structure, just indicate the positions of the ligand donor atoms (Circle your (b) What type of isomerism is exhibited by the molecule shown below? answer.) transmerd cis fac Page 39 of 47

Answer 1

HN NH3 tae-isomer meridon-isomer In case of face-isomes , 3 legaonds are present along the face of the complex white in moridonal , 3 identical ligands are present along a meridian Cis-isomer trans-isomer Trans-cis - isomers are shown by the given complex since two ligards are different
