REPULSION THEORY)  \nWhat is VSEPR Theory?  \nVSEPR theory was developed in 1947 by Gillespie andNyholm .This theory predicts molecular shape and bond angles more accurately.It states that “the lone pair and shared pair arrange themselves around the central atom in space as far apart as possible to minimize the electrostatic force of repulsion.”  \nThe Valence Shell Electron Pair Repulsion Theory abbreviated as VSEPR theory is based on the premise that there is a repulsion between the pairs of valence electrons in all atoms, and the atoms will always tend to arrange themselves in a manner in which this electron pair repulsion is minimalized. This arrangement of the atom determines the geometry of the resulting molecule.  \nPostulates of VSEPR Theory:  \nThe postulates ofthe VSEPR theory are listed below:--  \n1. Total number of electron pairs around the central atom = ½ (number of valence electrons of central atom + number of atoms linked to central atom by single bonds)  \n􀁸 For negative ions, add the number of electrons equal to the units of negative charge on the ions to the valence electrons of the central atom.  \n􀁸 For positive ions, subtract the number of electrons equal to the units of positive charge on the ion from the valence electrons of the central atom.  \n2. The number of Bond pair = Total number of atoms linked to central atom by single bonds.  \n3. Number of lone pairs = Total number of electron – No of shared pair  \nThe electron pairs around the central atom repel each another and move so far apart from each another that there are no greater repulsions between them. This results in the molecule having minimum energy and maximum stability.  \n􀁸 The shape of a molecule with only two atoms is always linear.  \n􀁸 For molecules with three or more atoms, one of the atoms is called the central atom and other atoms are attached to the central atom.  \n􀁸 If the central atom is linked to similar atoms and is surrounded by bond pairs of electrons only, the repulsions between them are similar as a result the shape of the molecule is symmetrical and the molecule is said to have regular geometry.  \n􀁸 If the central atom is linked to different atoms or is surrounded by bond pair as well as alone pair of electrons, the repulsion between them is similar. As a result, the shape of the molecule has an irregular or distorted geometry.  \n􀁸 The exact shape of the molecule depends upon the total number of electron pairs present around the central atom.  \nThe following terms are commonly used in discussing the shapes of molecules.  \n􀁸 Bond Angle: This is the angle between a bonded atom, the central atom, and another bonded atom.  \n􀁸 Lone Pair: This refers to a pair of valence electrons that are not shared with another atom.  \n􀁸 Molecular Geometry: This is the 3-D arrangement of bonded atoms in a polyatomic ion or molecule.  \n􀁸 Electron Pair Geometry: This is the 3-D arrangement of electron pairs around the central atom of a polyatomic ion or molecule.  \nUsing the VSEPR Chart to Determine Shape and Bond  \nAngle  \nTo use a VSEPR table, first determine the coordination number or number of electron pairs.  \n1. Count the valence electrons of the central atom.  \n2. Add an electron for each bonding atom.  \n3. Subtract an electron if the central atom has a positive charge; and add an electron for a central atom with negative charge.  \n4. Halve your count to get the total electron pairs.  \nFinally, look up your molecule on the chart by coordination number and number of atoms.  \nAlternatively, you can count the lone electron pairs, which are also indicated on the chart.  \nExample: PCl5  \nOnce you know PC","cbCaiqsMKwVBz6RG","https://ap.wps.com/l/cbCaiqsMKwVBz6RG","pdf",781411,"English","# VSEPR Theory\n## What is VSEPR Theory?\n## Postulates of VSEPR Theory\n## Terms Used in Molecular Shapes\n## Using the VSEPR Chart to Determine Shape and Bond Angle\n## Example: PCl5\n## VSEPR Chart Table\n## Limitations of VSEPR Theory\n# References","[{\"question\":\"What is VSEPR theory and what does it predict?\",\"answer\":\"VSEPR theory predicts molecular shape and bond angles by assuming electron pairs arrange around the central atom to minimize repulsion.\"},{\"question\":\"How are total electron pairs, bond pairs, and lone pairs calculated in VSEPR?\",\"answer\":\"Total electron pairs are 1/2 (valence electrons of the central atom + number of single-bonded atoms), with adjustments for ionic charge.
