Question
Select the correct statements about the VSEPR and hybridization approaches to the study of molecular geometry. The basis of the VSEPR model is that electron pairs in the valence shell of an atom attract one another. Electron pairs are referred to as electron domains. The basis of the VSEPR model is that electron pairs in the valence shell of an atom repel one another. Electron pairs are referred to as electron domains. To explain the bonding in some molecules, the concept of hybridization, or the mixing of atomic orbitals to form hybrid orbitals, is needed. Hybrid orbitals are used to predict molecular geometries. Molecular geometry is the arrangement of electron domains around the central atom. Molecular geometry is the arrangement of bonded atoms.Explanation / Answer
VSEPR stands for Valence Shell Electron Pair Repusion. Before this theory there was no direct relationship that existed between moloecular formula of a compound and shape of its molecule. The VSEPR theory is used to predict the geometry of a molecule.It involves predicting the arrangement of electron pairs around a non-hydrogen atom.Identification of electron pair in the valence shell of a central atom is determined with the help of lewis structure.This theory assumes that each atom within a molecule will tend to achieve a geometry which will help in minimizing the replusion between electron in the valence shell of the respective atom.
In VSEPR theory the electron pairs are referred to as electron domains. These electron pairs in most of the cases are mostly the lone pairs of an atom. It helps in determing the geometry of a particular molecule.
Hence, the 2nd option: THe basis of VSEPR model is that electron pairs in the valence shell of an atom repel one another. Electron pairs are referred to as electron domains. is the right option
