| (B) Solution of ethanol and water | (II) Dimerizes |
| (C) Solution of benzene and toluene | (III) Maximum boiling azeotrope |
| (D) Solution of acetic acid in benzene | (IV) ΔVmix = 0 |
Choose the correct answer from the options given below :
Solution
<p>To correctly match the items from List - I with those in List - II, let's analyze the characteristics of each solution:</p>
<p><p><strong>(A) Solution of chloroform and acetone:</strong> This solution exhibits negative deviation from Raoult's law. It creates a maximum boiling azeotrope because the interactions between chloroform and acetone molecules are stronger than those in the pure components.</p></p>
<p><p><strong>(B) Solution of ethanol and water:</strong> This solution shows positive deviation from Raoult's law, leading to the formation of a minimum boiling azeotrope. The interactions between ethanol and water molecules are weaker than those in their pure states.</p></p>
<p><p><strong>(C) Solution of benzene and toluene:</strong> This combination forms an ideal solution where Raoult’s law is obeyed across all concentrations. Thus, the volume change upon mixing, denoted as $\Delta V_{\text{mix}}$, is zero.</p></p>
<p><p><strong>(D) Solution of acetic acid in benzene:</strong> In this mixture, acetic acid tends to dimerize. The acetic acid molecules pair up, forming dimers, especially in non-polar solvents like benzene.</p></p>
<p>Based on these explanations, the correct matches are: </p>
<p><p>(A) - (III)</p></p>
<p><p>(B) - (I)</p></p>
<p><p>(C) - (IV)</p></p>
<p><p>(D) - (II)</p></p>
