Which forces of attraction are responsible for liquefaction of `H_(2)`?

Options

A. Coulombic forces
B. Dipole forces
C. Hydrogen bonding
D. van der Waals forces

Explanation

To determine the forces of attraction responsible for the liquefaction of hydrogen gas (H₂), we need to analyze the various intermolecular forces that can play a role in this process. Here’s a step-by-step breakdown:

### Step 1: Understanding Liquefaction
Liquefaction is the process of converting a gas into a liquid. This can be achieved by either lowering the temperature or increasing the pressure. During this process, intermolecular forces come into play.

**Hint:** Remember that gases have very weak intermolecular forces compared to liquids.
