Quick Answer: Why does water have a high boiling point compared to alcohol?

Why does water have higher boiling point than alcohol?

water has higher boiling point than alcohol because the extent of hydrogen bonding is stronger in water than in alcohol .

Why does water has high boiling point than ethanol Brainly?

Explanation: There are less extensive hydrogen bonding between ethanol molecules than between water molecules, thus less energy is needed to vaporise ethanol than water and water has a higher boiling point than ethanol.

Why does ethanol have a higher boiling point than Ethanethiol?

Note: However, ethanol molecules have a much more powerful intermolecular force available to them, which is hydrogen bonding. So, clearly, ethanol molecules have a higher boiling point or whatnot than ethanethiol.

Why do primary alcohols have higher boiling point?

From my understanding, for homologous alcohols, primary alcohols have the highest boiling points, because the OH group is the most accessible for other molecules to hydrogen bond to, therefore stronger intermolecular forces result in higher mp/bp.

Why does ethanol have a higher boiling point than methanol?

Ethanol has higher boiling point than Methanol. Boiling point of alcohol increase as the number of carbons increase. The factors affecting the boiling/melting points of alcohols are not only hydrogen bonds, but also van der Waals dispersion forces and dipole-dipole interactions.

Why does water have high melting point?

H2O has very strong intermolecular forces due to the hydrogen bonds that a formed within the compound. Usually this would mean the compound has a very high melting point as a large amount of heat energy is required to overcome the forces, however H2O has a melting point of only O degrees.

What explains the very high melting and boiling point of water?

Water has an unusually high boiling point for a liquid. … Water is made up of oxygen and hydrogen and can form hydrogen bonds, which are particularly strong intermolecular forces. These strong intermolecular forces cause the water molecules to “stick” to one another and resist transition to the gaseous phase.

Which of these typically increases when intermolecular forces increase?

As the intermolecular attraction increases, • The vapor pressure ( the pressure of the vapor that is in equilibrium with its liquid) decreases • The boiling point ( the temperature at which the vapor pressure becomes equal to the pressure exerted on the surface of the liquid) increases • Surface tension ( the …
