Limitations of vbt and cft
NettetMain assumptions of VBT: 1. The ligand → metal bond in a coordination complex is covalent in nature. It is formed by sharing of electrons (provided by the ligands) between the central metal atom and the ligand. 2. Each ligand should have at least one filled orbital containing a lone pair of electrons. 3.

NettetLIMITATIONS ( CFT ) : ... COMPARISON OF CFT AND VBT. Some of the belongingss of composites which could non be explained on the footing of valency bond theory are satisfactorily explained by crystal field theory.CFT is therefore decidedly an betterment over vbt these are the following virtues of cft over vbt will turn out that statement: NettetShow More. Molecular Orbital Theory (MOT): The VBT has two most serious limitations that electrons in molecules are treated as though they are localised and behave almost as they did in isolated atoms. This means that the VBT retains the individuality of the atoms composing molecule. The problem can be resolved by introducing the resonance ...

It’s a chemical bonding theory that explains how atoms create various chemical connections. This theory describes how chemical bonds are formed by overlapping or mixing atomic orbitals. money down drain imageNettet1 Crystal Field Theory (C.F.T.) Postulates of crystal field theory are: (i) In a coordination compound there are electrostatic interaction between metal atom/ion and ligands.
