Interpretation: The formulas and space filling models of the given molecules are to be examined. The correctness of each structure is to be checked. The correct structure is to be sketched for incorrect structures.
Concept Introduction: A Lewis structure is used to represent the valence electrons and the bonds present in a molecule.
Dots in the Lewis structure represent the valence electrons.
Total number of electrons for Lewis structure can be calculated by summing the valence electrons of each atom in the molecule.
Once a Lewis structure is drawn, it is possible to identify the shape of the molecule using the VSEPR theory.
VSEPR stand for Valence Shell Electron Pair repulsion theory. It uses chemical formula, number of bonds and lone pairs to predict the shape of molecules.
The geometry of a molecule or a polyatomic ion is determined on the basis of the total number of electron groups, the number of bonding groups and the number of lone pairs. To determine the geometry of the molecule, follow the following table:
