Question

Which of the following statements is incorrect postulates of VSEPR theory?

• A. The shape of a molecule depends upon the number of valence shell electron pairs (bonded or non-bonded) around the central atom
• B. Pairs of electrons in the valence shell repel one another since their electron clouds are negatively charged
• C. These pairs of electrons tend to occupy such positions in space that minimise repulsion and thus maximise distance between them
• D. The valence shell is taken as a sphere with the electron pairs localising on the spherical surface at minimum distance from one another

Answer 1

Answer: (D)

Statement (d) is incorrect.
It's correct form is as follows :
Valence shell is taken as a sphere with the electron pairs localising on the spherical surface at maximum distance from one another.
Rest other statements are correct.
