Choose the correct answer from the options given below:
| List I (Crystalline Solids) | List II (Examples) |
|---|---|
| (A). Ionic Solid | (I). $\text{CO}_2$ |
| (B). Covalent Solid | (II). $\text{K}_2\text{SO}_4$ |
| (C). Molecular Solid | (III). K |
| (D). Metallic Solid | (IV). Quartz |
- Correct answerA(A) - (II), (B) - (IV), (C) - (I), (D) - (III)
- B(A) - (III), (B) - (IV), (C) - (I), (D) - (II)
- C(A) - (I), (B) - (II), (C) - (IV), (D) - (III)
- D(A) - (III), (B) - (I), (C) - (IV), (D) - (II)
Solution
Ionic solids are formed by the electrostatic attraction between cations and anions. $\text{K}_2\text{SO}_4$ is an ionic solid composed of $\text{K}^+$ and $\text{SO}_4^{2-}$ ions.
Covalent or network solids consist of atoms held together by a continuous network of covalent bonds. Quartz ($\text{SiO}_2$) is a classic example of a covalent solid.
Molecular solids are composed of discrete molecules held together by intermolecular forces. Solid $\text{CO}_2$ (dry ice) is a molecular solid held together by London dispersion forces.
Metallic solids consist of a lattice of positive metal ions in a sea of delocalized electrons. Potassium ($\text{K}$) is a metallic solid.
Thus, the correct matching is (A) - (II), (B) - (IV), (C) - (I), (D) - (III).
Answer: (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
