The hydrogen chloride is a gas at room temperature due to the presence of weak intermolecular forces.
<h3>What is hydrogen chloride?</h3>
Hydrogen chloride (HCl) is a chemical compound in which polar covalent bond is present between hydrogen atom and chlorine atom.
This bond is not so strong enough to maintain the stability in the liquid phase, else they are weak intermolecular forces and easily gets break through small amount of energy and having low boiling point. That's why HCl is present in gaseous state at room temperature.
Hence due to weak intermolecular force, HCl is present in gaseous state.
