Diamond and solid rhombic sulphur both are covalent solids but the latter has very low melting point than the former. Explain why ?

Text Solution

Verified by Experts

Diamond is three dimensional net work covalent solid with strong interatomic forces whereas sulphur is a molecular solid consisting of puckered eight membered rings `(S_8)` held together by weak van der Waals forces.
