Question

Give an example of each molecular solid and an ionic solid?

Answer 1

Hint: Molecular solids are made up of the same or identical molecules. In the case of an ionic solid, they have charged ions that are anions and cations as their compositions. One can think about the possible examples which can have these properties.

Complete step by step answer:
1) First of all we will try to understand the molecular solids and ionic solids concept. The molecular solids have solid molecules of the same molecule as its composition.
2) The molecular solids can be classified as the polar molecular solids and the non-polar molecular solids. The polar molecular solids have a large electronegativity difference between its atoms in the molecule. The non-polar molecular solids have a less electronegative difference.
3) Now let us see the example of molecular solids. Water $\left( {{H_2}O} \right)$ is a polar molecular solids and sucrose $\left( {{C_{12}}{H_{22}}{O_{11}}} \right)$ is a non-polar molecular solid. One can write both the examples for molecular solids.
4) Now let us discuss the ionic solids. The ionic solids are the solids that have ions in its composition. The ions such as cation and anion are present in it which means these solids have charges in their composition.
5) The ionic solids contain generally a smaller-sized positive ion which is a cation and a larger-sized negatively charged ion which is an anion. An excellent example of an ionic solid is Salt $\left( {{\text{NaCl}}} \right)$ which has a composition as $N{a^ + }$ and $C{l^ - }$ ions.

Note:
The molecular solids are held together by the presence of intermolecular forces instead of bonds such as an ionic bond, covalent bond, etc. In the case of ionic solids, they are held together by the bond which is an ionic bond.
