Vedclass · Answer

(C) In $diamond$,each carbon atom is $sp^3$ hybridized and bonded to $4$ other carbon atoms in a rigid,three-dimensional tetrahedral network. This structure prevents the movement of atoms,making it extremely hard.In $graphite$,each carbon atom is $sp^2$ hybridized,forming planar hexagonal layers. These layers are held together by weak $van \ der \ Waals$ forces,which allow the layers to slide over each other,making $graphite$ soft.

Diamond is extremely hard whereas graphite is soft. This is because
