Valence Shell Electron Pair Repulsion (VSEPR) theory provides surprisingly simple explanations in terms of the electron pairs that surround the central atom of a given molecule. VSEPR theory is described in detail in every introductory chemistry book. ...
Which statement best describes VSEPR theory? The most stable arrangement keeps the atoms and. lone pairs of electrons as far away from each other as possible. The most stable arrangement keeps the lone pairs of electrons as far away from each other...
To predict the structures of the given species using VSEPR theory, we will follow these steps for each compound: calculate the number of electron pairs, determine the hybridization, and predict the geometry.1. For SO₃²⁻ (Sulfat

(i) Structure of SO3: In gaseous state SO3 has a plane triangular structure with O–S–O bond angle 120°. Solid SO3 exists in three types of structures. One form of structure is ice like and is a cyclic trimer (SO3)3 or ...
VSEPR theory that has its utility in predicting the shape of the molecules was first coined by Sidgwick and Powell in the year 1940. Later on, this theory was developed by Nyholm and Gillespie in the year 1957. The need for VSEPR theory arose because the Lewis approach proved to be ...
