Expert Answer:

Polar compounds are mostly ionic compound.
In these compounds, the bonding atoms have large difference in their electronegativities. Hence, one atom has a positive charge and the other carries negative charge which induces polarity in the molecule.
 
Polar molecules can be identified from the type of bonding atoms in the structural formula of the molecule. If the bonding atoms contains one highly electropositive and the other is highly electronegative then the molecule is polar molecule.
For example: NaCl molecule. Sodium is highly electropositive while chlorine is highly electronegative. Hence, it is a polar molecule.
