A) Boiling points
B) Vapour pressure at the same temperature
C) Heat of vaporization
D) Gaseous densities at the same temperature and pressure
Correct Answer: D
Solution :Gaseous density of both ethanol and dimethyl ether would be same under identical condition of temperature and pressure while the rest of these three properties vapour pressure, boiling point and heat of vaporization will differ as ethanol has hydrogen bonding where as ether does not.
