Draw the Dot structure of graphite in free electron??

Dear student,

In graphite, each carbon atom is bonded to three other carbon atoms in the same plane giving a hexagonal array. One of these bonds is a double-bond, and thus the valency of carbon is satisfied. Graphite structure is formed by the hexagonal arrays being placed in layers one above the other.

Structure of graphite.

Due to this these layers can slip over each other so graphite has a slippery surface. Hence it is used as a lubricant.
