Question

Explain draw backs of electronic theory of valance?​

Answer 1

Answer:

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

Answer 2

Helo Mate here your ans

Every elements has a tendency to occupy inert gas, because it is considered as the most configuration ( stable octet)..........

plz thx my ans and Mark me brainliest plz....
