Question

For which of the following parameters the structural isomers $C_2H_5OH$ and $CH_3OCH_3$ would be expected to have the same values? (Assume ideal behaviour)

• A. Heat of vaporization
• B. Gaseous densities at the same temperature and pressure
• C. Boiling points
• D. Vapour pressure at the same temperature

Answer 1

Answer: (B)

Gaseous densities at the same temperature and pressure

Answer 2

$\because$ the molecular weight of $C_2H_5OH$ & $CH_3OCH_3$ are same so in its vapour phase at same temperature & pressure the densities will be same
