Structure and Bonding of Carbon
This question is about carbon and its various structures.
Fullerenes are molecules of carbon atoms with hollow shapes. The first fullerene to be discovered was buckminsterfullerene (C60C_{60}C60).
What shape is a buckminsterfullerene molecule?
Give one use of buckminsterfullerene.
Methane is a compound of carbon and hydrogen.
Below is a representation of the dot-and-cross diagram of a methane molecule:
Complete the displayed formula of methane by drawing single bonds (lines) to represent the four single covalent bonds around the carbon atom:
HHCHH \begin{array}{ccc} & \text{H} & \\ \text{H} & \text{C} & \text{H} \\ & \text{H} & \end{array} HHCHHDetermine the molecular formula of methane.
Methane is a gas at room temperature and has a low boiling point. Why does methane have a low boiling point?
Select one option:
- The covalent bonds are strong.
- The covalent bonds are weak.
- The intermolecular forces are strong.
- The intermolecular forces are weak.
Graphene is a single layer of graphite.
Explain why graphene:
- is a good electrical conductor,
- has a very high melting point.
You should answer in terms of structure and bonding.
