It is based on the simple fact that electron pairs (bonded and non-bonded pairs) maximize their distances to minimize repulsions. The regions of space where the electrons are most likely tobe found are referred to as electron domains. The arrangement of the electron domains about the central atom of a molecule or ion is called the electron-domain geometry. The molecular geometry is the arrangement of the nuclei in space. In VSEPR Theory we predict the molecular geometry (its molecular shape) from its electron-domain geometry. To apply VSEPR Theory to predict molecular shape, use the following guidelines.  \n1) First: Draw the Lewis structures.  \na) Draw a skeletal structure to show the arrangement of the atoms. Often smaller more electronegative atoms surround larger less electronegative atoms.  \nb) Find the total number of valence electrons. If the species is an ion, subtract one electron for each unit of positive charge and add one electron for each unit of negative charge.  \nc) Assign two electrons to each covalent bond.  \nd) Distribute the remaining electrons so that each atom surrounding the central atom has the appropriate number of non-bonded electrons to complete octets (duplets if they are hydrogen atoms) . Put any remaining electrons pairs around the central atom. There are three exceptions to the octet rule to be aware of:  \ni) Species with an odd number of valence electrons, like NO, NO2 and ClO2 .  \nii) Electron de􀀌cient compounds like Be, B and Al.  \niii) Expanded valence shells, with more than eight electrons around the central atom. Such structures are possible only when the principal quantum number of the valence electrons of the central atoms is n 􀀕 3. (i.e. the central atom is in period  \n3 or greater with available d orbitals)  \ne) If there are not enough electrons to go around form multiple bonds. Multiple bonds can be written between atoms of C, N, O, P and S. If the central atom is B, Be or Al do not form multiple bonds. These atoms are electron de􀀌cient.  \nf ) There are also many molecules and ions for which it is not possible to draw a single Lewis structure that is an adequate representation of the bonding. Such molecules or molecular ions involve the concept of resonance. It is possible, however, to think of one or more structures that satisfy the octet rule. These are the called the resonances structures or canonical forms. The term resonance structure is somewhat of a misnomer since it gives the impression of vibration or oscillation in common language. Nothing like this is involved when we write resonance structures. The actual structure is a resonance hybrid of the resonance structures or canonical forms. In a resonance hybrid the electron density is delocalized over the entire molecule or ion rather than being localized between two atomic nuclei. It should be emphasized that the necessity of introducing the concept of resonance is due solely as our inability to represent the bonding with a single drawing using the rules for Lewis structures. The experimental evidence of bond lengths and bond strengths of the actual structure do  \nChemistry 135 Semester 022012 VSEPR Theory  \nnot support the Lewis representations of the 􀀌ctitious resonance structures. Draw the resonance structures for SO2 , SO23–, CO23– and O3 .  \n2) Second: Determine the electron-domain geometry as either linear, trigonal planar, tetrahedral, trigonal bipyramidal or octahedral. Notice there are only 􀀌ve electron-domain geometries but as many as thirteen usual molecular geometries.  \n3) Third: Use the arrangement of the bonded atoms to determine the molecular geometry. Draw the Lewis structures and molecular shapes for each of the examples in the table below. Predict the bond angles within each and every structure.  \nTotal  \n2 3  \n3 4  \n4 4  \n5 5  \n5 5  \n6 6  \n6  \nBonding 2  \n3 2  \n","cbCaia1ZUNXu3dNf","https://ap.wps.com/l/cbCaia1ZUNXu3dNf","pdf",34444,"English","# VSEPR Theory\n## Predicting Molecular Shape from Electron Domains\n## Steps for Applying VSEPR (Lewis Structures to Geometry)\n## Electron-Domain vs Molecular Geometries and Bond Angles\n## Key Notes and Exceptions","[{\"question\":\"What is the core idea behind VSEPR theory?\",\"answer\":\"VSEPR theory predicts molecular shape using the idea that electron pairs (bonded and non-bonded) maximize their distances to reduce repulsion.
