Sir,while predicting the shape of coordination entities using VBTwe need to write the hybridisation of the metal and for that we need to know whether it is paramagnetic or diamagnetic? How to know that just by seeing the formula compound? Please explain.
While predicting the shape of coordination entities using VBT. We need to write the hybridization of the metal. For that we need to know whether the ligands are strong or weak. Strong field ligands lead to low spin complexes with almost diamagnetic or very low paramagnetism whereas weak field ligands lead to high spin complexes with paramagnetic behaviour. Just by seeing the ligand in the coordination complex, you can predict to an extent. But the actual magnetic moment is determined only after writing the hybridization. For eg.,
