**VSEPR theory** stands for Valence Shell Electron Pair Repulsion which tackles on the resulting geometry of molecule according to the number of electron pairs surrounding their central atoms.

The general formula of compounds indicating electron groups is

**AX _{n}E_{m}**

Where A is the central atom

X represents the atoms attached to A

n is the number of atoms attached to A

E represents the lone pairs around A

m is the number of lone pairs around A

To determine the molecular shape, we must first draw the Lewis Structure

Use the VSEPR or the hybridization method to predict the bond angles in the following molecules. Show your reasoning.

a. SO_{2}

b. SO_{3}

c. SO_{3}^{2–}
