Fullerenes

Cards (6)

What are fullerenes
Large carbon molecules
Fullerenes are not giant covalent structures. What are they?
Large molecules shaped like hollow balls or tubes - different fullerenes contain different numbers of carbon atoms
How are the carbon atoms in fullerenes arranged
In rings, similar to those in graphite
Why can fullerenes conduct electricity
Just like graphite, they have delocalised electrons
Bigger molecules have bigger ? forces
Bigger intermolecular forces
Why are fullerenes' melting and boiling points high for molecular substances
Because they're big molecules - meaning that they have more intermolecular forces but no where near as high as graphite and diamond
