Q. Assertion: The dipole moment helps to predict whether a molecule is polar or non-polar.
Reason: The dipole moment helps to predict geometry of molecules.

AIIMSAIIMS 1999Chemical Bonding and Molecular Structure

Solution:

The linear triatomic molecules of the type $B - A - B$ e.g.

$CO _{2}$ have no dipole moment, not because the individual $C = O$ bonds are non-polar but because the two bond moments (polarity) cancel each other.

Therefore, geometry of molecules can be predicted by the value of dipole moment.
