Final answer:
Yes, the concept of Weak and Strong Field Ligands is applicable in Valence Bond Theory.
Step-by-step explanation:
Yes, the concept of Weak and Strong Field Ligands is applicable in Valence Bond Theory. Valence bond theory explains the number of bonds formed in a compound and the relative bond strengths. When ligands interact with a metal ion, they can be classified as either weak field or strong field ligands. The classification depends on the ability of the ligands to cause energy splitting of the metal ion's d orbitals.
Strong field ligands cause a large energy splitting, favor low spin complexes, and completely fill the t2g orbitals before occupying the eg orbitals. Weak field ligands cause a smaller energy splitting, favor high spin complexes, and singly occupy both the t2g and eg orbitals before any are doubly occupied.
