How many of the following are bent in shape?
SO2, O3, I3-, N3-
SO2, O3, I3-, N3-
Solution and Explanation
SO2 (Sulfur Dioxide) has a bent molecular geometry due to the presence of a lone pair of electrons on sulfur atom, which distorts the molecular shape.
O3 (Ozone) has central oxygen atom is surrounded by two unshared electrons (one lone pair) and six bonding electrons (three bonds). So it is bent in shape.
I3- (Triiodide ion), and N3- (Azide ion) are linear.
Therefore,
SO2 (Sulfur Dioxide) - Bent shape
O3 (Ozone) - Bent shape
I3- (Triiodide ion) - Linear shape
N3- (Azide ion) - Linear shape
So, Two molecules/ions, SO2 and O3, have a bent shape. The other two, I3- and N3-, have a linear form.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
