Polar molecules have positive and negative ends (charges) while non-polar molecules don’t because their charges cancel out.

Molecular geometry is the arrangement of bonded atoms.  If no lone pairs are present, the molecular geometry is the identical to the electron domain geometry.

Step 2

The molecular shape of a molecule tells whether it is polar or not

For example: non-polar molecule,
