Answer:
Increasing vapor pressure order -
propane > dimethyl ether > ethanol
Explanation:
Vapor pressure - the pressure exerted the gaseous molecules , on the walls of the container is called the vapor pressure.
Boiling point - the temperature at which the the vapor pressure of the liquid equals the external atmospheric pressure.
Both boiling point and vapor pressure are linked by the inter molecular forces between the atoms.
The compound with stronger inter molecular forces are tightly held , hence more amount of energy is required to vaporize. Therefore, higher boiling point , and in turn the vapor pressure will be lower .
And the compound with weaker inter molecular forces are loosely held , hence less amount of energy is required to vaporize. Therefore, lower boiling point , and in turn the vapor pressure will be higher .
Therefore,
Ethanol has lowest vapor pressure , because at lower temperature , it has H - bonding , hence, its boiling point is more, therefore, less vapor pressure.
Dimethyl ether has vapor pressure more than ethanol as it has weaker dipole - dipole interactions as compared to strong H - bonding .
Propane has maximum vapor pressure among all , because of lower molecular mass than others , it can easily vaporize into vapors.
Hence,
Increasing vapor pressure order -
propane > dimethyl ether > ethanol
The Increasing vapor pressure order of vapor pressure for the liquids listed in the question is; propane > dimethyl ether > ethanol.
The vapor pressure of a liquid shows how easily the liquid is converted to vapor. Liquids that are easily converted to vapor are said to have a low vapor pressure.
The Increasing vapor pressure order of vapor pressure for the liquids listed in the question is; propane > dimethyl ether > ethanol. This is because, propane has the least intermolecular interaction and ethanol has the highest degree of intermolecular interaction among the molecules in the list.
