Vedclass · Accepted Answer

In it,carbon atoms are linked by strong bonds in plates containing large hexagonal rings,and these layers are held together by weak inter-layer bonds.

Vedclass · Answer

(D) Graphite has a layered structure where each carbon atom is $sp^2$ hybridized and covalently bonded to three other carbon atoms in the same layer,forming hexagonal rings. These layers are held together by weak van der Waals forces,which allows the layers to slide over each other,making graphite a soft solid lubricant. The strong covalent bonds within the layers require a very high temperature to break,making it extremely difficult to melt.

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