Identify the correct statement(s) regarding the fundamental postulates of Valence Bond Theory (VBT) — Coordination Compounds Chemistry Question

💡 Solution & Explanation

(A) True: VBT postulates that ligands (Lewis bases) donate lone pairs to the empty hybrid orbitals of the metal (Lewis acid) forming coordinate covalent (dative) bonds. (B) True: Complexes using $(n-1)d$ orbitals are inner orbital complexes, and those using $nd$ orbitals are outer orbital complexes. (C) False: The electrostatic point-charge model is the basis of Crystal Field Theory (CFT), not VBT. (D) False: VBT assumes coordinate covalent bonding, and hybrid orbitals are highly directional, determining the complex's specific geometry.
