Briefly, water has two set of hydrogen atoms for every one atom of oxygen in a molecule. From these two hydrogen atoms, it can form hydrogen bonding with other oxygen atoms of other water molecules. From this, since hydrogen bonding is the strongest type of intermolecular forces, it will require alot of energy to break these hydrogen bonds in between the molecules of water causing the significantly high rise in the melting and the boiling point of water.

What is the connection between the size of the molecules in crude oil and their condensing or boiling point's?
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
Which of the following nonpolar molecules has the highest boiling point (N2C2H4F2O2 or CS2)?
The molecule N2C2H4F2O2 has a higher boiling point.
Are there more water vapor molecules above a beaker of water at room temperature or a beaker of water at its boiling point?
There are more water vapor molecules above a beaker of water at its boiling point because the higher temperature causes more water molecules to evaporate into the air. This results in a higher concentration of water vapor over the boiling water compared to room temperature water.
What relation does the boiling point of an amine have to a similar hydrocarbon?
The boiling point of an amine is typically higher than a similar hydrocarbon due to the presence of intermolecular hydrogen bonding between amine molecules. This hydrogen bonding results in stronger attractive forces between amine molecules, requiring more energy to overcome and reach the boiling point.
Why is the boiling point of H2O higher than boiling point of H2S?
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.

How does pressure affect boiling point?
An increase in pressure raises the boiling point of a liquid because it takes more energy for the liquid molecules to escape the higher atmospheric pressure above them. Conversely, decreasing the pressure lowers the boiling point as it requires less energy for the molecules to overcome the reduced atmospheric pressure.
Why the boiling point of water higher than the boiling point of Ethan?
The boiling point is the temperature at which a liquid will change into a gas. This happens when the molecules have enough energy to break the bonds holding them in close proximity. Since water molecules have a stronger attraction to each other than ethane molecules have for each other, water needs to be heated to a higher temperature to break these bonds.
What has a higher boiling point alcohol or water?
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.
Why is acid anhydride having higher boiling point than alkane?
Molecules with dipoles have higher boiling points because they are able to form strong dipole-dipole interactions with other molecules. Alkanes are nonpolar and only have weak London dispersion forces, thus lower boiling points.
Are there more water vapor molecules above a beaker of water at room temperature or a beaker of water at its boiling point?
There are more water vapor molecules above a beaker of water at its boiling point because the higher temperature causes more water molecules to evaporate into the air. This results in a higher concentration of water vapor over the boiling water compared to room temperature water.

The boiling point of an amine is typically higher than a similar hydrocarbon due to the presence of intermolecular hydrogen bonding between amine molecules.

Why is the boiling point of H2O higher than boiling point of H2S?
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
How does the boiling point in degrees Celsius of a saltwater solution compare to the boiling point of normal tap water?
The boiling point of a saltwater solution is higher than that of normal tap water because the presence of salt raises the boiling point. Salt molecules disrupt the formation of water vapor molecules during boiling, requiring more energy to break the bonds and reach the boiling point.
What has a higher boiling point water or KI?
Potassium iodide has a higher boiling point because it is ionically bonded while water is polar covalent (with hydrogen bonds). The ionic bonds on KI are stronger than the bonds of water. This means that the molecules are "stuck" to each other stronger than water's molecules. Then it would take more energy (heat) to "unstick" them to change its state of matter, resulting in a higher boiling point.
Why does ethanol has a higher boiling point?
Ethanol has a higher boiling point than methane because ethanol molecules are larger and have stronger intermolecular forces such as hydrogen bonding, making it more difficult for the molecules to break free from each other and vaporize.
