(a)
Interpretation:
Molecules that contain only nonpolar bonds have to be classified as polar, nonpolar, or polarity cannot be determined due to insufficient information.
Concept Introduction:
Measure of the degree of inequality in attraction of the bonding electrons to the various locations present within a molecule is known as molecular polarity. This can also be said in terms of electron attraction and that is in a molecule one part is favored than the other parts of the molecule.
If in a molecule there is an uneven distribution of electronic charges means it is known as polar molecule. If there is a symmetrical distribution of electron charge over the molecule means it is known as nonpolar molecule. Two factors that decide molecular polarity is bond polarity and geometry of molecule. If a molecule is symmetrical means then there won’t be any molecular polarity because the effect given by the polar bonds may cancel out each other.
(b)
Interpretation:
Molecules that contain two polar bonds only have to be classified as polar, nonpolar, or polarity cannot be determined due to insufficient information.
