According to the General Steps for determining if a molecule is polar or nonpolar, what is considered the bond polarity if the difference in electronegativity for the atoms in a bond is greater than 0.4?

• The bond is essentially nonpolar.

• The bond is polar.

• The bond is ionic.

• The bond polarity cannot be determined with this information.

If a molecule has no polar bonds, what is the polarity of the molecule?

• The molecule is polar.

• The molecule is nonpolar.
