Question
- A. Water (H2O)
- B. Diamond
- C. Sodium chloride (NaCl)
- D. Carbon dioxide (CO2)
Answer
Diamond
Explanation
Diamond is a giant covalent structure where each carbon atom is bonded to four other carbon atoms through strong covalent bonds.
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.
