Question
- A. Weak intermolecular forces
- B. Strong covalent bonds
- C. Presence of ions
- D. Metallic bonding
Answer
Strong covalent bonds
Explanation
The high melting points of giant covalent structures are due to the presence of strong covalent bonds that require significant energy to break.
Common mistake
Misunderstanding melting points
Students often think that giant covalent structures have low melting points because they are made of non-metal atoms.
Emphasize that giant covalent structures are held together by many strong covalent bonds, which require a lot of energy to break, resulting in very high melting points.
