For which of the following parameters the structural isomers C2H5OH and CH3OCH3 would be expected to have the same values? (Assume ideal behavour)
Correct answer: D. Gaseous densities at the same temperature and pressure
- A. Boiling points
- B. Vapour pressure at the same temperature
- C. Heat of vaporization
- D. Gaseous densities at the same temperature and pressure
Explanation
Gas density is defined as the mass of the gas occupying a certain volume at specified pressure and temperature. Gaseous densities of ethanol and dimethyl ether would be same at same temperature and pressure because they have the same masses. The heat of vaporization, V.P. and b.pts will differe due to H - bonding in ethanol.
