Question

What is the main drawback of VSEPRT? ​

Answer 1

Answer:

The two main limitations of VSEPR theory include: Bond Angle Deviations: In the cases of methane and water, VSEPR predicts them both to be tetrahedral in shape. However, because of the bent shape of water, the bond angle is far less than that of methane and is something that VSEPR theory can't account for numerically.

Answer 2

One of the main limitations of VSEPR theory is that it cannot predict the degree to which bond angles may deviate from idealized cases.
