Because hydrogen is an element but hydrogen chloride is a polar compound so needs more energy to overcome the permanent dipole bonds. :)
Only a liquid can boil. HCl boils at -84.9C
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.
HI has a higher boiling point because of the dipole-dipole Intermolecular forces as well as the dispersion forces, which become more evident with molecular weight, which will dominate over the dipole-dipole forces, so HCl has a lower boiloing point.
Adding sodium chloride to water increases the boiling point of the solution. This is because the presence of salt disrupts the hydrogen bonding between water molecules, making it harder for the water to vaporize at the boiling point.
Boiling Point:1500C (2732F) Sublimes.

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 boiling point of sodium chloride is 1 413 0C.
801 degrees Celsius This is incorrect.! Actually it has a boiling point of 1413 degrees Celsius or 2575 F.

Sodium chloride has a higher boiling point.
The boiling point of sodium chloride is 1 413 0C and it is not so low.
Water and hydrogen chloride are both polar compounds (which is to say, the molecule has both positive and negative poles) but water is more polar than hydrogen chloride. Oxygen has a higher electronegativity than chlorine does, and consequently, there is a greater difference in electronegativity between oxygen and hydrogen than there is between chlorine and hydrogen. Consequently, there is a greater concentration of electrons at the oxygen atom than at the chlorine atom in these two molecules. Polarity then leads to attraction between molecules (which align themselves so that negative poles can attract positive poles) and greater attraction between molecules will result in a higher boiling point.
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.
