Problem 70

Given information

A molecule with four bonding groups and one lone pair on the central atom is given. 

Step-by-step explanation

VSEPR theory is also called the Valence Shell Electron Pair Repulsion Theory.  It is mainly involved in the prediction of the molecular shape or geometry of the molecule with the help of the number of bond pairs or lone pairs present in it.

According to VSEPR theory, the presence of lone pair on the central atom of a molecule causes deviation from standard molecular geometry. Thus, valence electrons provide Lewis structure, which gives an idea about electron pair geometry and hybridization.
