Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(B) C₆₀(s) is a molecular solid: This is correct. Fullerene molecules are held together by weak van der Waals forces, which is the defining characteristic of a molecular solid.

(A) Graphite vs. Diamond: Incorrect. Diamond has a higher thermal conductivity than graphite due to its rigid 3D lattice and strong covalent bonding.

(C) Red Phosphorus: Incorrect. The polymer shown is red phosphorus, but black phosphorus is the thermodynamically most stable allotrope of phosphorus.

(D) Purity of Fullerene: Incorrect. Fullerene is considered the purest form of carbon because it has a closed cage structure with no dangling bonds, unlike graphite or diamond.
