None of the above
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.
Final Answer
The intermolecular force present in \(\mathrm{H}_2\) is:
\[
\boxed{\text{London dispersion}}
\]
