Explanation:
NB: The boiling point of the liquids given are referred to as their normal boiling point i.e the boiling point at atmospheric pressure.
The relationship between normal Boiling point and vapor pressure is that; at a given temperature the lower the normal boiling point, the higher the vapor pressure.
hence ether with the least normal boiling point of 35°C is expected to have the largest vapor pressure near room temperature.
