**Explanation of Diagrams:**

- **Formic Acid Structure:** The Lewis structure shows a carbon atom (C) double-bonded to an oxygen atom (O), with an OH (hydroxyl) group and a hydrogen atom (H) bonded to the carbon. The diagram illustrates the connectivity and electron pairs that facilitate hydrogen bonding in formic acid.

**Key Points:**

- Methane (CH₄) does not engage in hydrogen bonding within its own molecules or with water molecules.
- Formic acid participates in hydrogen bonding within its own molecules thanks to the presence of the hydroxyl (OH) group.
- Hydrogen fluoride (HF) exhibits hydrogen-bonding forces both within its own molecules and with water molecules due to its highly polar nature.

This table helps in visualizing and understanding the presence of hydrogen bonds in various chemical compounds.
