Only a liquid can boil. HCl boils at -84.9C
At the standard temperature and pressure, hydrogen chloride exists as a gas. It does not exist in liquid state, but in aqueous medium along with water as a solvent.
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 20.268 K (-252.88 °C or -423.184 °F)The freezing point of hydrogen is 14.025 K (-259.125 °C or -434.425 °F).
Liquid hydrogen has a boiling point of -252.87 degrees Celsius.

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.
Hydrogen fluoride (HF) is a gas at room temperature, but does have a higher boiling point than hydrogen chloride (HCl). Flourine is more electronegative than chlorine, so the HF molecule is more polar than the HCl molecule. This makes them more strongly attracted to one another (somewhat in the manner of magnets) and boiling a substance involves overcoming that intermolecular attraction.
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.
The small size and high electronegativity of Fluorine is responsible for high polarity in HF molecules this high polarity is responsible for strong hydrogen bonding with in HF molecules so high amount of heat is required to convert the liquid HF into gaseous state and hence it has high boiling point as compare to HCl.Polar.
