Why Does Water Have a Higher Boiling Point Than Ethanol

- April 20, 2022

Water has higher boiling point than alcohol because the extent of hydrogen bonding is stronger in water than in alcohol. Hence water has higher boiling point at same atmospheric pressure than ethanol.

Moreover we know that water freezes into ice at 273 k and changes into vapour states at 373 K.

. Why does water have a higher. Thus water has a higher boiling point. Check your inbox for more details.

Water has higher boiling point than alcohol because the extent of hydrogen bonding is stronger in water than in alcohol. In a solution of water and ethanol hydrogen bonding is the strongest intermolecular force between molecules. Moreover we know that water freezes into ice at 273 k and changes into vapour states at 373 k.

Why water has higher boiling point than ethyl alcohol. In a solution of water and ethanol hydrogen bonding is the strongest intermolecular force between molecules. There are less extensive hydrogen bonding between ethanol molecules than between water molecules thus less energy is needed to vaporise ethanol than.

Water has higher boiling point than alcohol because the extent of hydrogen bonding is stronger in water than in alcohol Moreover we know that water freezes into ice at 273 k and changes into vapour states at 373 k. Water can form two hydrogen bonds due to there being 2 delta posotive hydrogens incurred by the electronegative oxygen atom. Water needs higher energy to break those bonds.

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. Water therefore has more permanent-permanent dipole attractions which take more energy to break than the energy required to break the intermolecular bonds in ethanol.

I HOPE THIS HELP U PLEASE GIVE ME THUMBS UP AND MARK ME IN BRAIN LIST. Intermolecular hydrogen bondings are strong and hence require a large amount of energy to break these hydrogen bonds. Keeping this in view why is the boiling point of water higher than ethanol.

Oxygen is highly electronegative. Well begun is half done. You can score higher.

Hence the difference in boiling points. Ethanol has an OH- attached to the carbon chain. Water has a higher boiling point that alcohol ethanol.

The main reason for this is because water has stronger intermolecular forces holding the molecules together. Because 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. You have joined No matter what your level.

Hydrogen bonding occurs when the partially negative oxygen end of the molecules is attracted to the partially positive hydrogen eng of the molecule. This means that greater energy is needed to pull an ethanol molecule out of the liquid than that for a molecule of propane. That is why the boiling point of ethanol is higher.
