We’re being asked to identify the compounds with polar bonds and are polar molecules.


Recall that the polarity of a bond depends on the electronegativity difference between two atoms:

ΔEN

Polarity

0.0 < x < 0.50

Nonpolar covalent

0.50 ≤ x < 2.0

Polar covalent

2.0 ≤ x

Ionic


A polar bond results in a dipole moment. The net dipole is the sum of all dipole moments in a molecule:

polar molecule: has a net dipole 

nonpolar molecule: has no net dipole


A compound with only nonpolar bonds is a nonpolar molecule.


For each compound, we need to:

Step 1: Determine the polarity of the bonds.

Step 2: Determine the polarity of the molecule.
