Question

define VSPER theory

briefly with examples

Answer 1

Definition: VSEPR is the acronym for Valence Shell Electron Pair Repulsiontheory. VESPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom.

Answer 2

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 is the acronym for Valence Shell Electron Pair Repulsion theory. VESPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom. 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.

example ;) - Shape of molecules/ions where central atom is surrounded by three atoms/ions:

Type: AB3 (3bp) and AB2 (2 bp and 1 lp)

Example of such molecule is BF3, GaCl3 etc with three bonding electron pairs and SnCl2, PbCl2 etc. with two bonding pairs and one lone pair. They have trigonal planar or angular or V - shape.
