Concept Introduction:

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.

The polarity and net dipole moment of the molecule can be checked with the dipole of each bond and also the symmetry of molecule because even with polar bonds, a symmetrical molecule can be non-polar.
