Bonds are viewed as weakly connected orbitals in the Valence bond theory (small overlap). In general, valence bond theory is easier to apply to ground-state ...

In case the atomic orbitals possess more than one unpaired electron, more than one bond can be formed and electrons paired in the valence shell cannot take part ...

3 июл. 2021 г. · Limitations of VB theory: It does not explain the colour of the complex. It considers only the spin only magnetic moments and does not ...

26 дек. 2023 г. · VBT is limited in predicting molecular geometry. It doesn't provide a systematic approach for determining the three-dimensional arrangement of atoms.

Limitations of Valence Bond Theory · Failure to explain the tetravalency exhibited by carbon. · No insight is offered on the energies of the electrons. · The ...

1. Failure to explain the color of coordination compounds: VBT fails to explain the color exhibited by coordination compounds.

The valence bond theory has the following limitations : (1) It cannot explain the spectral properties (colours) of the complex compounds.

15 мая 2023 г. · Valence bond theory only explains the formation of a covalent bond in which a shared pair of electrons comes from two bonding atoms. However, it ...

30 дек. 2023 г. · The structure of the complexes predicted from the VBT would not always match necessarily with those determined from the experiments.
