Question

what is Draw
back of vbt?
​

Answer 1

Answer:

What are the shortcomings of VBT? The valence bond theory fails to explain the tetravalency of carbon and also fails to provide insight into the energies corresponding to the electrons. The theory also assumes that the electrons are localized in certain areas.

Answer 2

Answer:

hope it works

Explanation:

The VB theory explains the formation, structures and magnetic behaviour of coordination compounds, it suffers from the following shortcomings:

(i) It involves a number of assumptions.

(ii) It does not give quantitative interpretation of magnetic data.

(iii) It does not explain the colour exhibited by coordination compounds.

(iv) It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.

(v) It does not make exact predictions regarding the tetrahedral and square planar structures of 4-coordinate complexes.

(vi) It does not distinguish between weak and strong ligands.
