QUESTION (2006:1)

Molecules of water(H₂O) and ozone (O₃) each contain 3 atoms and both themolecules are bent. However, the bond angle in H₂O is significantly smaller than the bond angle in O₃.

Using Lewis structures, discuss thereasons for the differencein bondangles of these two molecules.

The Lewis structure for hydrogen chloride, HCl, is
