Question

Explain VSEPR theory along with postulates?


need quality answer ☑️​

Answer 1

The VSEPR theory is used to predict the shape of the molecules from the electron pairs that surround the central atoms of the molecule. The VSEPR theory is based on the assumption that the molecule will take a shape such that electronic repulsion in the valence shell of that atom is minimized.

VSEPR Theory:

• VSEPR theory mean Valence Shell Electron Pair Repultion Theory

• It was proposed by sidgwick and Powell and improved by Gillespie and Nyholm

Postulates:

• In covalent compound, bonds and lone pairs repel one another and stay as far apart as possible

• The total no. of bonds and lone pairs around the central atom help us to predict the arrangement of bonds and shape of the molecules.

• Repulsion order: Lone pair - lone pair > Lone pair - Bond pair > Bond pair - Bond pair.

• The molecule will re adjust itself to get minimum repultion
