The pair of boiling point and compound are given as, The pair of boiling point and compound are given as, Which will show lowest vapour pressure at room temperature? Which will show lowest vapour pressure at room temperature?

Options

  1. AC6H6\mathrm{C}_6 \mathrm{H}_6
  2. BCH3OH\mathrm{CH}_3 \mathrm{OH}
  3. CC6H5NO2\mathrm{C}_6 \mathrm{H}_5 \mathrm{NO}_2
  4. DC6H5NH2\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2

Correct answer

C. C6H5NO2\mathrm{C}_6 \mathrm{H}_5 \mathrm{NO}_2

Step-by-step solution

As boiling point is inversely proportional to vapour pressure. Hence, nitrobenzene having bp 212∘C212^{\circ} \mathrm{C} will show lowest vapour pressure at room temperature.
