Vedclass · Answer

(D) In graphite,each $C$ atom is covalently bonded to three other carbon atoms in a hexagonal layered structure,which accounts for its high melting point.These hexagonal layers are held together by weak van der Waals forces,allowing them to slide over each other with minimal mechanical force.Due to this property,graphite acts as a soft solid lubricant.

Graphite is a soft solid lubricant and is extremely difficult to melt. What is the reason for this behavior of graphite?
