question
in order for a molecule to be polar, it must have:
select the correct answer below:
polar covalent bonds
a net dipole
asymmetry
all of the above

Explanation:

Polar covalent bonds create charge - separation. Asymmetry in a molecule prevents bond - dipole cancellation, leading to a net dipole. A net dipole is characteristic of a polar molecule. So all these factors are required for a molecule to be polar.

Answer:

D. all of the above
