Molecules Flashcards
1
Q
What are the properties of simple covalent molecules?
A
They have a micromollecular lattice
Weak forces of attraction so have low boiling points.
2
Q
What are the properties of giant covalent molecules?
A
They have a macromolecular lattice
No forces of attraction, only covalent bonds so high boiling point.
