Question

Name the force that accounts for the softness of graphite. (Refer to the diagram)

Answer 1

Weak Van der Waals forces between two hexagonal layers of graphite is responsible for its softness .
Hope it helps .

Answer 2

⇒Graphite is unique because of its structure. It has layers in its structure. The layers are basically planar in shape and are made up of hexagonal rings of carbon atoms.

⇒These layers are bound together by Van der Waal's weak forces.

⇒Due to this weak force, the layers could slide over one another.

⇒This characteristic makes the graphite a little bit soft.
