Question

Explain Valency Shell Electron Pair Repulsion (VSEPR) theory?

Answer 1

Valence shell electron pair repulsion (VSEPR) theory is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.

hope this may help ...............

Answer 2

Answer:

Valence Shell Electron pair repulsion : -

(1) Sidgwick and Powell proposed valence shell electron pair repulsion theory to predict the shapes of covalent molecules

(2) It is based on idea that the electron pairs on the atoms in a molecule repel each other

(3) The atoms in a molecule arrange themselves in such a way that repulsion is minimised.

(1) The arrangement of electrons is called electron pair geometry
