Your question: Why does water have a high boiling point?

Why does water have a high boiling point and melting point?

High boiling point and low melting point. Water has strong hydrogen bonds between molecules. These bonds require a lot of energy before they will break. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces.

Why does H2O have higher boiling point?

Water molecules form a bulky molecule and it is very difficult to break its bonds. To break all its bonds, a large amount of the energy is required. Thus, $H2O$ has a higher boiling point than HF.

Where would water have the highest boiling point?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.

What has a higher boiling point than water?

Because oxygen is more electronegative than carbon, an O-H bond has a larger bond dipole than a C-H bond. Hence the force of attraction between two water molecules is greater than it is between two methane molecules. Water has the higher boiling point. Now let’s compare methane and dihydrogen.

Why is KBr boiling point so high?

For KBr: The compound involves a metal cation (K+) and a nonmetal anion (Br). Hence, KBr is an ionic compound and possesses ionic bonding. Ionic bond is stronger than the covalent bonds present in CH3Br. Therefore, KBr is expected to have a higher boiling point than CH3Br.

Does KF have a higher melting point than KBr?

The ionic compound with the highest melting point is KF.

Which has a higher melting point k2o or MgO?

Oscar L. MgO has the highest melting point, by a large margin.
