Answer:

1.Sulfur dioxide (SO2) is polar in nature. The electronegativity difference between sulfur (2.58) and oxygen (3.44) atoms makes it a polar molecule.

2.Nitrogen gas (N2) is diatomic and non-polar because both nitrogen atoms have the same degree of electronegativity. If there are no dipoles, what would make the nitrogen atoms stick together to form a liquid? London dispersion forces allow otherwise non-polar molecules to have attractive forces.

3.In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).

4.CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.

5.Neon (Ne) is a noble gas, nonpolar and with only modest London Dispersion forces between atoms. Intermolecular Forces 1. (B) the lower the boiling point. The strength of LDF's depend on the polarizability of the molecules, which in turn depends on the number of electrons and the area over which they are spread.
