Question

Which of the following is a network solid?

• A. $S{O}_2$ (Solid)
• B. $I_2$
• C. Diamond
• D. $H_{2}O$ (Ice)

Answer 1

The correct option is C Diamond

a) In $S{O}_2$, molecules are held together by dipole-dipole interaction. It is an example of polar molecular solids.
b) In $I_2$, molecules are held together by van der waal's forces. It is an example of non-polar molecular solids.
c) Diamond is an example of network solid or covalent solid. It has three dimensional network solid in which atoms are connected by covalent bonds.
d) $H_{2}O$ (Ice) is an example of Hydrogen Bonded Molecular Solids. In this type of solid, molecules are held together by hydrogen bonding.
