These forces actually exist between all the molecules and are not of much importance while we talk about intermolecular bonding in HCl. The other type of intermolecular force present between HCl molecules is the London dispersion force. Therefore, two opposite charges or poles develop inside the same molecule that is also referred to as a dipole.Īs the positively charged hydrogen end of one molecule comes in contact with the negatively charged chlorine end of another molecule, intermolecular attraction forces come into the picture, which is known as the dipole-dipole interaction. The chlorine atom being more electronegative acquires a partial negative charge by pulling the shared electron pair towards itself while the hydrogen atom attains a partial positive charge. This bond is formed owing to the electronegativity difference between hydrogen and chlorine due to which two separate poles develop inside the molecule. In the HCl molecule, the hydrogen atom and the chlorine atom are bonded through a polar covalent bond. The London dispersion forces occur amongst all the molecules.Ĭonclusion Why does HCl have a low boiling point? The attraction forces that arise between the slightly positive hydrogen atom of one molecule and the slightly negative chlorine atom of another molecule are known as dipole-dipole interaction. HCl has the dipole-dipole interaction and London dispersion forces present in between its molecules.ĭue to the electronegativity difference between hydrogen (2.2) and chlorine (3.16), a slight positive charge develops on the hydrogen atom while the chlorine atom acquires a slight negative charge. What types of intermolecular forces are present in HCl? In this article, you will learn everything you need to know about the intermolecular forces in HCl. Hey Readers!!! Welcome to another fresh article on techiescientist. It is used in the production of a number of inorganic compounds, in the pickling of steel, in pH control and neutralization reactions, etc. It is also found as a component of gastric acid in the stomach of humans as well as some other animals. In the industries, hydrochloric acid is prepared by reacting hydrogen chloride with water. it contains one atom of hydrogen and one atom of chlorine. It is denoted by the chemical formula HCl i.e. Hydrochloric acid is a colorless, pungent-smelling liquid.
