Strutural isomers `C_2H_5OH` and `CH_3OCH_3` have the same value of

Options

A. boiling points
B. heat of vaporization
C. gaseous densities at the same temperature and pressure
D. vapor pressure at the same temperature

Answer

C

Explanation

`C_2H_5OH` exhibits intermolecular H bonding while `CH_3OCH_3` does not exhibit intermolecular H bonding Thus, they have different values of (1), (2), and (4) becase of same molecular mass, they have same gaseous dendities at the same T and `P(d=(PM)/(RT))`
