Topic Summary: Simple Molecules
Key Terms
- Simple molecular: small molecules with covalent bonds within and weak forces between
- Intermolecular forces: weak attractions BETWEEN molecules
- Intramolecular bonds: strong covalent bonds WITHIN molecules
Must-Know Facts
- Low MP/BP — weak intermolecular forces break (not covalent bonds)
- Do NOT conduct — no ions or free electrons
- Often gases or liquids at room temperature
- Larger molecule = more intermolecular forces = higher MP
- Examples: H₂O, CO₂, O₂, N₂, CH₄, NH₃, Cl₂
