Current Question (ID: 17910)

Question:
$\text{The pair having only molecular solids among the following is -}$
Options:
  • 1. $\text{Brass and SiC}$
  • 2. $\text{Ammonium phosphate (NH}_4\text{)}_3\text{PO}_4$
  • 3. $\text{SiC and plastic}$
  • 4. $\text{Tetra phosphorus decoxide (P}_4\text{O}_{10}\text{) and I}_2$
Solution:
$\text{HINT: A molecular solid is composed of molecules held together by van der Waals forces, dipole-dipole interactions, and hydrogen bonding.}$ $\text{Explanation:}$ $\text{Ionic solid} \rightarrow \text{Ammonium phosphate (NH}_4\text{)}_3\text{PO}_4$ $\text{Metallic solid} \rightarrow \text{Brass}$ $\text{Molecular solid} \rightarrow \text{Tetra phosphorus decoxide (P}_4\text{O}_{10}\text{) and I}_2$ $\text{Covalent (network) solid} \rightarrow \text{SiC}$ $\text{Amorphous solid} \rightarrow \text{Plastic}$
