Question

Valence Shell Electron pair repulsion(VSEPR) theory

Answer 1

Answer:

VSEPR theory is based on the idea that the geometry (shape) of a molecule is mostly determined by repulsion among the pairs of electrons around a central atom. The pairs of electrons may be bonding or non-bonding .

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.

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