### Understanding Intermolecular Forces and Boiling Points

This educational guide explores the relationship between boiling points and intermolecular forces of various molecules. The table below is designed to be completed with research and analysis.

#### Instructions:
1. **Look up the values for the boiling points on the internet.**
2. **Predict all the different kinds of intermolecular forces present and explain why you think these are present. Finally, underline the strongest IMF.**
3. **Explain the trend seen in this table.**

#### Table of Molecules:

| Molecule | Boiling point (°C) | Intermolecular forces present |
|----------|-------------------|-------------------------------|
| CH₄      |                   |                               |
| C₂H₆     |                   |                               |
| HCl      |                   |                               |
| HF       |                   |                               |
| H₂O      |                   |                               |

#### Molecules to Investigate:
- **Methane (CH₄)**
- **Ethane (C₂H₆)**
- **Hydrochloric acid (HCl)**
- **Hydrofluoric acid (HF)**
- **Water (H₂O)**

#### Educational Objectives:
- Learn the concept of intermolecular forces (IMF) including London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
- Analyze how IMFs affect the boiling points of substances.
- Discover trends in boiling points relative to molecular structure and types of bonding.
