TM substitution Flashcards
which metal complex does partial substitution
Cu
which ligands are the same size
H2O and NH3
which is the bigger ligand
Cl-
when can ligand substitution reactions not be reversed easily
when the new complex is much more stable
which ligand bonds more strongly to Fe than H2O
CN-
what type of ligand is more stable in new complex
multidentate form more stable complexes
why are some reactions 0 enthalpy change
bonds formed same enthalpy as bonds broken / the same bonds
what is the chelate effect
the increase in stability caused by monodentate ligands being substituted for multidentate ligands, because when monodentate are substituted for multidentate, the number of particles in solution increases as more monodentate ligands than multidentate which are now in the complex. more particles means greater entropy and so more likely to occur
what is the coordination number of EDTA4-
6 (coordinate bonds formed)
