For which of the following parameters the structural isomers $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$ and $\mathrm{CH}_3 \mathrm{OCH}_3$ would be expected to have the same values? (Assume ideal behaviour)
  1. Heat of vaporization
  2. Gaseous densities at the same temperature and pressure
  3. Boiling points
  4. Vapour pressure at the same temperature

Solution

$\because$ the molecular weight of $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH} \& \mathrm{CH}_3 \mathrm{OCH}_3$ are same so in its vapour phase at same temperature \& pressure the densities will be same
