Question

Which of the following is network solid?

• A. $S{O}_{2\left(solid\right)}$
• B. $I_2$
• C. Diamond
• D. $H_2{O}_{\left(ice\right)}$

Answer 1

Answer: (C)

Diamond

A network solid or covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material. In a network solid there are no individual molecules, and the entire crystal or amorphous solid may be considered a macromolecule.

In diamond, the carbon atoms are held together by strong covalent bonds. It is a giant molecule. Thus, it is a network solid.

So, option $C$ is correct.
