Hint: Diamond is an example of a crystalline solid in which the carbon atoms are arranged in a well-defined order. In Diamond, each tetravalent carbon atom is fused with four carbon atoms, and each of these four carbon atoms are further linked with four other carbons.
Complete Step by Step Solution:
Crystalline solid
- The crystalline solid or crystal belongs to the class of solid material.
- Inside the crystalline solid the constituent particles such as atoms, molecules, and ions are arranged in very well defined uniform order in all directions.
- The crystalline solids possess sharp melting points along with well-defined faces and edges.
- The crystalline solids have an excellent tendency to diffract x-rays.
- The crystalline solids are also considered anisotropic in nature because their physical properties are different in all directions.
- Diamond, quartz, calcium fluoride (\[Ca{F_2}\]), silicon dioxide (\[Si{O_2}\]), and sugar are some of the best examples of such materials.
Because the crystalline solid has a perfect arrangement of the constituent particles at low temperatures. As the temperature increases, the well-organised arrangement of constituent particles gets perturbed and at this stage the crystalline solid changes into the liquid phase.
Therefore, from the above discussion, option (a) will be the correct answer.
Note: The crystalline solids have a wide range of applications. Diamond can be used in making beautiful jewelry whereas quartz is used in making watches and clocks.
