Question
Describe the structure of graphite.
✓
Answer
Graphite is composed of layers of two$-$dimensional sheets of carbon atoms.
Each sheet is made up of hexagonal net of $sp^2$ carbons bonded to three neighbours forming three bonds.
The fourth electron in the unhybrid $p-$orbital of each carbon is shared by all carbon atoms resulting in a $\pi$ bond. These it electrons are delocalized over the whole layer.
The $C – C$ bond length in graphite is $141.5 \ pm.$
The individual layers are held by weak van der Waals forces and separated by $335 \ pm.$
Graphite is soft and slippery and is thermodynamically most stable allotrope of carbon.
