how one can find hybridisation of complexes having strong field & weak field ligand both

6 years ago


Answers : (1)


Dear student,

There are two types of ligands namely strong field and weak field ligands. A strong field ligand is capable of forcing the electrons of the metal atom/ion to pair up (if required). Pairing is done only to the extent which is required to cause the hybridization possible for that co-ordination number. A weak field ligand is incapable of making the electrons of the metal atom/ ion to pair up.


Strong field ligands: CN, CO, en, NH3, H2O, NO, Py.


Weak field ligands: I, Br, Cl, F, NO3, OH, C2O42–, NH3, H2O.
