Question

Choose the molecule or compound that exhibits dispersion forces as its strongest intermolecular force. Choose the molecule or compound that exhibits dispersion forces as its strongest intermolecular force.

a. CO
b. O2
c. HCl
d. NaCl
e. All of these have intermolecular forces stronger than dispersion.

Answer 1

O2 - exhibits dispersion forces as its strongest intermolecular force.

Step-by-step explanation:

Generally speaking, all biatomic homonuclear molecules, such as N2, O2, F2, do NOT have any dipole moment: the distibution of the nuclear clouds is symmetrical. They are non-polar.

For what concerns heteronuclear molecules, it depends on their geometry.

Dispersion force ( Van der Waal)< dipole dipole < hydrogen bond

Intermolecular forces are forces of attraction between molecules/atoms based mainly on the idea of like charges repel and opposite charges attract.

Based on the polarity of the substance, the type of intermolecular forces existing between substance may be different.
