Which of the compounds below is an example of a network solid? O Sg (s) SiO2 (s) MgO (s) NaCl (s) O C25H52 (s)

SiO₂ (s) is an example of a network solid.

Explanation:

Network solids, also known as the covalent network solids, are the class of chemical compounds in which the constituting atoms are bonded covalently to form a continuous network, which extends through the material. In a network solid, there are no individual molecules and thus the whole solid is called a macromolecule.

Some of the examples of network solids are diamond and quartz.

Quartz or silicon dioxide is a three-dimensional continuous network of SiO₂ units.
