Question

______ is an example of a crystalline substance.

• A. Wax
• B. Sugar
• C. Tea

Answer 1

Answer: (A), (B)

Sugar

Crystalline substance

The substance in which the particles are arranged in a regular pattern is called a crystalline substance.

The explanation for the correct answer

(a) Wax

Wax is very soft and thus included in molecular solids. They are molecular crystals in which intermolecular forces are Vander Waal forces.

(b) Sugar

Sugar is arranged in a regular pattern and its chemical formula is ${\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}$.

The explanation for the incorrect answer

(c) Tea

Since tea is not arranged in a regular pattern, it is not an example of a crystalline substance.

Therefore, wax and sugar are examples of crystalline substances.
