Current Question (ID: 18133)

Question:

$\text{The type of inter-molecular interactions present in:}$ $\begin{array}{|c|c|} \hline \text{(a)} & \text{n-Hexane and n-octane} & \text{(i)} & \text{Van der Waal's forces of attraction} \\ \text{(b)} & \text{NaClO}_4 \text{ and water} & \text{(ii)} & \text{Ion-dipole interaction} \\ & & \text{(iii)} & \text{Dipole-dipole interaction} \\ \hline \end{array}$

Options:

1. $(a) \ (i) \ \ (b) \ (ii)$
2. $(a) \ (ii) \ \ (b) \ (iii)$
3. $(a) \ (iii) \ \ (b) \ (i)$
4. $(a) \ (iii) \ \ (b) \ (ii)$

Solution:

$\text{Hint: Nonpolar compound shows van der Waal intermolecular force}$ $\text{n-Hexane and n-octane are the nonpolar compounds. The intermolecular force of attraction between nonpolar compounds is weak van der Waal forces.}$ $\text{NaClO}_4 \text{ gives Na}^+ \text{ and ClO}_4^- \text{ ions in the solution while water is a polar solvent. In the water molecules, the dipole is present. So, water molecules show ion-dipole interaction with Na}^+ \text{ and ClO}_4^- \text{ ions.}$
