Question

For which of the following parameters the structural isomers `C_(2)H_(5)OH` and `CH_(3)OCH_(3)` would be expected to have the same values (Assume ideal behaviour)
A. Boiling points
B. Vapour pressure at the same temperature
C. Heat of vaporization
D. Gaseous densities at the same temperature and pressure

Answer 1

Correct Answer - D
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, boiling point and heat of vaporization will differ as ethanol has hydrogen bonding whereas ethers does not.
