Web12 aug. 2024 · Valence bond theory explains the bonding in co-ordination compounds. VBT proposed by Pauling and The main postulates of valence bond theory are: (1) The central metal ion makes available a number of empty orbitals for accommodating electrons donated by the ligands. WebThe valence bond theory is an attempt to describe the covalent bonding between atoms. It assumes that atoms are able to share electrons in order to fill their outer shells. In most … In chemistry, valence bond (VB) theory is one of the two basic theories, along with molecular orbital (MO) theory, that were developed to use the methods of quantum mechanics to explain chemical bonding. It focuses on how the atomic orbitals of the dissociated atoms combine to give individual chemical bonds when a molecule is formed. In contrast, molecular orbital theory has orbitals that cover the whole molecule. interstellar played live
