Hydrogen chloride (HCl) is a gas at room temperature due to its low boiling point (-85°C). In comparison, hydrogen chloride dissolved in water forms hydrochloric acid (HCl) which is a liquid.
Hydrogen and hydrogen chloride have different boiling points because they are different molecules with different molecular structures. Hydrogen chloride has stronger intermolecular forces (dipole-dipole interactions) compared to hydrogen, leading to a higher boiling point. These forces hold the molecules of hydrogen chloride together more tightly, requiring more energy to overcome them and change from liquid to gas.
The boiling point of liquid hydrogen is approximately -252.9 degrees Celsius or 20.3 Kelvin.
Liquid hydrogen has a boiling point of -252.87 degrees Celsius.

Hydrogen chloride has weaker intermolecular forces, allowing it to exist as a gas at room temperature, while hydrogen fluoride has stronger intermolecular forces, making it a liquid under the same conditions. Specifically, hydrogen fluoride can form hydrogen bonds between molecules, leading to a higher boiling point compared to hydrogen chloride.
Hydrogen chloride exists as a gas at room temperature due to its low boiling point of -85 degrees Celsius. This means that at room temperature, the molecules have enough kinetic energy to overcome the intermolecular forces holding them together as a liquid. Therefore, hydrogen chloride remains in the gaseous state.
Water has hydrogen bonding between molecules, which requires more energy to break compared to the weaker van der Waals forces between hydrogen chloride molecules. The stronger hydrogen bonding in water results in a higher boiling point compared to hydrogen chloride.
Hydrogen chloride has a higher boiling point than diatomic fluorine because it forms stronger intermolecular forces due to hydrogen bonding. Hydrogen chloride molecules can form dipole-dipole interactions, while fluorine molecules only experience weak van der Waals forces. As a result, hydrogen chloride requires more energy to overcome these forces and transition from a liquid to a gas.
The boiling point of sodium chloride is 1 413 0C.
Sodium chloride (NaCl) has a higher boiling point than urea. This is because sodium chloride forms ionic bonds which are stronger than the hydrogen bonds in urea. Stronger bonds require more energy to break, resulting in a higher boiling point.
Hydrogen fluoride has a higher boiling point than hydrogen chloride because HF molecules have stronger hydrogen bonding due to the smaller size and higher electronegativity of the fluorine atom. This results in stronger intermolecular forces in HF compared to HCl, requiring more energy to break the bonds and reach the boiling point.
