Acetone is more volatile than ethanol.
Yep
Ethylamine is more volatile than methylamine.
water is more polar than acetone
Gasoline is more volatile than diesel.
There are two factors which determine the vapor pressure of ethanol (because what makes ethanol volatile is that it was a high vapor pressure).What makes the vapor pressure of ethanol quite high is that it is a small molecule with a low molecular weight. In fact, if you look at other molecules with similar size and weight, many of them are gases at room temperature. The molecular weight of ethanol (C2H5OH) is approximately 46 grams/mole. Carbon dioxide (CO2) has a molecular weight of 44 grams/mole, but it is a gas. Butane, C4H6 has a molecular weight of 54 g/mol and is a gas. Chlorine (Cl2) is a gas with molecular weight of 71 g/mol! So you might predict that ethanol should be a gas at room temperature from this.However, ethanol is a liquid. The reason it is a liquid is because it can hydrogen bond. The alcohol group, -OH, in the molecule has both a hydrogen bonded to an oxygen atom, which is allows for hydrogen bonding. Hydrogen bonding is a very strong intermolecular force, and this is what makes ethanol a liquid (and water too, which has a molecular weight of only 18 g/mol -- water is not volatile because it has two -OH groups, and so can hydrogen bond much better than ethanol can).So ethanol is volatile because it is a small and light molecule, but it is not as volatile as you might otherwise expect due to hydrogen bonding.
ethanol
Ethanol boiling point: 78.37 °C Methanol Boiling point: 64.7 °C Acetone Boiling point: 56 to 57 °C dichloromethane Boiling Point: 39.8-40.0°C Water Boiling Point: 100°C dichloromethane more volatile than the others
Ethanol is more polar than acetone because in acetone the carbon that the O is bonded to is sp2 hybridized where as the carbon that the O is bonded to in ethanol is sp3 hybridized. Since the sp2 carbon is more polar than the sp3 carbon, acetone has a lower dielectric constant. Hope this helps.
The three liquids have different densities. Water has a density of 1g/mL. Acetone has a density of 0.791g/mL. Ethanol has the density of 0.789g/mL. Also, ethanol has the strong smell that resembles one of nail polish remover. Ethanol is used in alcohol. Acetone is practically a type of acid.
as ethanol is an alcohol containing polar group in its structure that is OH it is a polar group.As acetone is a carbonyl compound containig two CH3 groups which are non polar and Carbonyl group is slightly polar compared to alcoholic group so ethanol is highly polar than acetone
It is not cooler, it feels cooler because acetone is far more volatile than water, so it absorbs more heat from your skin when you feel it evaporating from the skin (using it as nail polish remover)
Ethylamine is more volatile than methylamine.
water is more polar than acetone
Water expands more than ethanol because the boiling point og water is more than that of ethanol.
Gasoline is more volatile than diesel.
May be because it gives more volatile esters, easy to separate or concentrate or strip off.

Methanol is more polar because is capable of dipole-dipole interactions AND hydrogen bonding while acetone is capable of just dipole-dipole interaction.
