As we have learned

Valence bond theory (VBT) -

  1. Ligands should have atleast one donor atom with a lone pair of elements.
  2. Transition metal atom provide required number of vacant orbitals.
  3. These vacant orbitals undergo hybridiation.
  4. These hybridised orbitals overlap with filled orbitals of ligands to form coordinaate compound.
