JEE Main 2025 — Solutions Question with Solution

A binary mixture of ${\text{C}}_6{\text{H}}_5\text{OH}$ and ${\text{C}}_6{\text{H}}_5{\text{NH}}_2$ exhibits negative deviation from Raoult's law. This means that the vapor pressure of the solution is lower than the vapor pressures of the pure components, ${\text{C}}_6{\text{H}}_5\text{OH}$ and ${\text{C}}_6{\text{H}}_5{\text{NH}}_2$. Consequently, the boiling point of the solution is higher than the boiling points of the pure substances. Therefore, this mixture forms a maximum boiling azeotrope.
