Explain with the concept of hybridization and VSEPR theory, how sulphate ion and sulphite ion are formed.

 

Plz also state the number of sigma-bonds and pi-bonds in each ion and show how the oribital of oxygen atom overlap with the oribital of sulphur.

Valence Shell Electron Pair Repulsion theory (VSEPR) states that rules govern the shape of a molecule once it has been isolated.  The electrons that surround the molecule push away from one another.  Common molecular shapes identified include: linear, bent, diagonal planar, pyramidal, and tetrahedral.  In order to minimize electron repulsion the distance between the electrons must be increased. Maximum means the greatest distance of the angles between the bonds.

Hybridization comes into play when a chemist looks at the molecules and manipulates their atomic orbitals to create the same number of hybrid orbitals.  In this manner the chemist is minimizing the electron distance.

Valence Shell Electron Pair Repulsion theory or VSEPR for abbrievation, is used in chemistry as a model for predicting the shape of individual molecules based on their electrostatic repulsion, where the valance electron pairs surrounding the molecule push away ( or repel) against each other, and to minimize the electrical repulsion forcing the electrons away from each other, in order to get the best electron arrangement or electron configuration, to shorten the electronic distance.

Hybridization comes into action, where it manipulates the electron orbitals in the molecule to form new hybrid orbitals, and to minimize the distance between the electrons
