alevel aqa chemistry transition metals
do I need to learn the full structure of EDTA and haemoglobin? is that likely to be asked in an exam question? I'm confused on if haemoglobin has a co-ordination number of 4 or 6. In class we learned that Fe forms 4 dative bonds to 4N atoms but in a revision video I'm watching it says Fe forms 4 with nitrogens from haem, 1 with a nitrogen from globin and 1 with either and oxygen atom or a water molecule. which one is correct?
