# 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 vaporisation

(b) Vapour pressure at same temperature

(c) Boiling points

(d) Gaseous densities at the same temperature and pressure.

Except the gaseous densities all other parameters are different because of the presence of H-bonding in alcohol and the absence of the same in ether.
Hence d is the correct answer.
