Graphite, diamond and Fullerene Flashcards
Why does graphite conduct electricity?
Graphite contains delocalised (free) electrons. these electrons are free to move between the layers in graphite therefore graphite conducts electricity.
Why are diamonds hard?
Because the carbon atoms in diamond are bonded in a stronger tetrahedron pattern
Why is graphite soft and slippery?
Because the carbon atoms in graphite are bonded in layers with only weak vanderwall force holding the layers together.
Why is C60 Fullerene suitable for doctors to use to delivery medicine?
C60 Fullerene is inert meaning it doesn’t react with other molecules or structures in the body.
Why does diamond have a higher melting point than C60 Fullerene?
Due to its structure of carbon-carbon double bonds, fullerene has weaker intermolecular forces compared to the strong covalent network in diamonds.
The many covalent bonds in diamonds are very strong therefore a large amount of temperature is needed to break them.
