17.17—Haemoglobin is an iron(II) complex containing a polydentate ligand and that ligand exchange occurs when an oxygen molecule

Know that haemoglobin is an iron(II) complex containing a polydentate ligand and that ligand exchange occurs when an oxygen molecule bound to haemoglobin is replaced by a carbon monoxide molecule The structure of the haem group will not be assessed.

Use —haemoglobin is an iron(ii) complex containing a polydentate ligand and that ligand exchange occurs when an oxygen molecule to connect the rule to the data and decision in the question.

This matters because —haemoglobin is an iron(ii) complex containing a polydentate ligand and that ligand exchange occurs when an oxygen molecule determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —haemoglobin is an iron(ii) complex containing a polydentate ligand and that ligand exchange occurs when an oxygen molecule to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Haemoglobin is an iron(II) complex containing a polydentate ligand and that ligand exchange occurs when an oxygen molecule is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
