Is ClO2 polar or nonpolar?
Understand the Problem
The question is asking whether the molecule chlorine dioxide (ClO2) is polar or nonpolar. To determine this, we will consider the molecular geometry and the electronegativity of the atoms involved.
Answer
ClO2- is polar.
Because of its bent shape and the presence of two polar O-Cl bonds and two lone pairs of electrons, ClO2- does not cancel out the dipoles, resulting in a net dipole moment. Thus, ClO2- is polar.

Because of its bent shape and the presence of two polar O-Cl bonds and two lone pairs of electrons, ClO2- does not cancel out the dipoles, resulting in a net dipole moment. Thus, ClO2- is polar.
More Information
The bent shape and lone pairs on chlorine result in an uneven distribution of charge, causing ClO2- to be polar.
Tips
Make sure to consider both molecular shape and bond polarity when determining a molecule's overall polarity.
