Compare5 marksStandard

Cis-platin, [Pt(NHX3)X2ClX2]\ce{[Pt(NH3)2Cl2]}, is a square planar complex used as a cancer drug. Another complex, [Co(NHX3)X4(HX2O)X2]X2+\ce{[Co(NH3)4(H2O)2]^{2+}}, is octahedral. Compare the types of stereoisomerism shown by these two complexes, and state whether each complex is overall polar or non-polar.

How this question is marked

5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.

Compare means: Give similarities or differences between two things, and say which side each point belongs to. Write each point as a pair, for example: A is X, whereas B is Y. Two separate descriptions rarely earn the marks.
