The boiling point of ${\mathrm{C}}_6{\mathrm{H}}_6, {\mathrm{CH}}_3\mathrm{OH}, {\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NH}}_2$ and ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NO}}_2$ are $80°\mathrm{C}, 65°\mathrm{C}, 184°\mathrm{C}$ and $212°\mathrm{C}$, respectively. Which one will show the highest vapour pressure at room temperature?

At $40°\mathrm{C}$, the vapor pressure (in torr) of methyl alcohol ($\mathrm{A}$) and ethyl alcohol ($\mathrm{B}$) solution is represented by
$\mathrm{P}=120 {\mathrm{X}}_{\mathrm{A}}+138$ where ${\mathrm{X}}_{\mathrm{A}}$ is mole fraction of methyl alcohol. The value of $\underset{{\mathrm{X}}_{\mathrm{A}}\to 0}{\lim }\frac{{\mathrm{P}}_{\mathrm{B}}^0}{{\mathrm{X}}_{\mathrm{B}}}$ and $\underset{{\mathrm{X}}_{\mathrm{B}}\to 0}{\lim }\frac{{\mathrm{P}}_{\mathrm{A}}^0}{{\mathrm{X}}_{\mathrm{A}}}$ are

When a plot of boiling point versus composition is plotted, then the type of graph that cannot be obtained is:

Which of the following graphs represents the behavior of ideal binary liquid mixture?

(Here, ${\mathrm{Y}}_{\mathrm{A}}$ and ${\mathrm{Y}}_{\mathrm{B}}$ are the mole fractions of components $\mathrm{A}$ and $\mathrm{B}$in vapour.)

On mixing $1$mole of ${\mathrm{C}}_6{\mathrm{H}}_6 \left({\mathrm{P}}^{\circ }=42 \mathrm{mm}\right)$ and $2$mole of ${\mathrm{C}}_7{\mathrm{H}}_{8 }\left({\mathrm{P}}^{\circ }=36 \mathrm{mm}\right)$, one can conclude

Benzene and naphthalene form an ideal solution at room temperature. For this process, the true statement(s) is (are)

In the following statements, which is/are false for a solution of chloroform and acetone?

Composition of an azeotrope
