Answer to Question #296676 in General Chemistry for aki6g

Question

Substance A melts at 2300 °c, and it doesn’t conduct electricity even when molten and doesn't dissolve in water. What is the structure and bonding of this?

Answer 1

All covalent network structures have very high melting points and boiling points because many strong covalent bonds need to be broken. They are all hard, and do not conduct electricity because there are no free charges that can move.
