Concept explainers
(a)
Interpretation:
The given molecules should be explained whether they polar or not.
Concept introduction:
When there is difference in electronegativity of the bonded atom which results in polar bond, then to the polar molecules.
When one molecule have more than one polar bond then definitely it must contain geometry, then that should be in asymmetric in at least one direction so that they do not cancel out each other.
Because dipole is a vector
(b)

The given molecules should be explained whether they polar or not.
