Solution

Solution Steps

Step 1: Identify the Molecule Type

The molecule in question is $\mathrm{H}_2$ , which is a diatomic molecule consisting of two hydrogen atoms. It is nonpolar because the two hydrogen atoms have the same electronegativity, resulting in an even distribution of electron density.

Step 2: Determine Possible Intermolecular Forces

For nonpolar molecules like $\mathrm{H}_2$ , the primary intermolecular force is London dispersion forces. These are weak forces that arise due to temporary fluctuations in electron density, which induce temporary dipoles in neighboring molecules.

Step 3: Evaluate Other Intermolecular Forces

Dipole-dipole interactions: These occur between polar molecules. Since $\mathrm{H}_2$ is nonpolar, dipole-dipole interactions are not present.
Hydrogen bonding: This specific type of dipole-dipole interaction occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine. $\mathrm{H}_2$ does not meet these criteria, so hydrogen bonding is not present.
None of the above: This option is not applicable because London dispersion forces are present.
