Question

If a compound has a very low melting and boiling point, it is likely that the compound possesses mainly which type of intermolecular force?

Dipole-dipole forces

Hydrogen bonding

London dispersion forces

Cannot determine from the information given

Answer 1

Answer:

C.

Explanation:

Dipole-dipole forces and hydrogen bonding are much stronger, leading to higher melting and boiling points.

Answer 2

Answer:

London dispersion forces

Explanation:

Melting and boiling point are properties of the matter that are determined by the intermolecular forces: the stronger the forces that pulls the molecules togeter the grater thei melting anf boiling points will be.

Dipole-dipole and Hydrogen bonding forces  are strong forces, but London dispersion forces are weak, so a compounf with a very low melting and boiling point, it is likely that its mainly intermolecular force is a London dispersion.
