Covalent network crystals have_____________?
Correct answer: C. higher melting point then molecular crystals
- A. discrete molecules linked by Van der waals forces
- B. lower melting point then molecular crystals
- C. higher melting point then molecular crystals
- D. hydrogen bonding
Explanation
Covalent network crystals contain atoms joined throughout a strong covalent framework, so breaking the structure requires much more energy than separating molecular crystals. They consequently have higher melting points than molecular crystals.
