Question
- A. Ionic bonds
- B. Covalent bonds
- C. Intermolecular forces
- D. Metallic bonds
Answer
Intermolecular forces
Explanation
Small molecular substances have weak intermolecular forces that are overcome during melting, allowing the molecules to move freely.
Common mistake
Covalent Bonds Misunderstanding
Students often think that covalent bonds are broken when small molecular substances melt or boil.
Students should understand that during melting or boiling, it is the weak intermolecular forces that are overcome, not the covalent bonds within the molecules.
