Vedclass · Answer

(D) network solid,also known as a covalent network solid,is a material in which atoms are linked by a continuous network of covalent bonds extending throughout the entire crystal structure.In such solids,there are no discrete individual molecules; instead,the entire crystal acts as a single macromolecule.Diamond consists of a three-dimensional network of carbon atoms,and $SiO_2$ (quartz) consists of a three-dimensional network of silicon and oxygen atoms.Conversely,$P_4O_{10}$,$P_4O_6$,and $SO_3$ are molecular solids consisting of discrete molecules held together by weak van der Waals forces.Therefore,the pair consisting of only network solids is Diamond and $SiO_2$.Hence,option $D$ is correct.

Which of the following pairs consists of only network solids?
