Detailed explanation-1: -Lewis structures are very useful in predicting the geometry of a molecule or ion. The valence shell electron-pair repulsion theory (abbreviated VSEPR) is commonly used to predict molecular geometry.
Detailed explanation-2: -The VSEPR theory is used to predict the shape of the molecules from the electron pairs that surround the central atoms of the molecule. The theory was first presented by Sidgwick and Powell in 1940.
Detailed explanation-3: -VSEPR model is a model in chemistry used to forecast the form or shape of the molecules by stating that pairs of electrons repel each other therefore staying far from each other.
Detailed explanation-4: -VSEPR Rules: Identify the central atom. Count its valence electrons. Add one electron for each bonding atom. Add or subtract electrons for charge (see Top Tip) Divide the total of these by 2 to find the total. number of electron pairs. Use this number to predict the shape.
