hydrogenhalid
Hydrogenhalide is a general term used to describe binary compounds of hydrogen and a halogen atom. The halogens are the elements in Group 17 of the periodic table: fluorine, chlorine, bromine, iodine, and astatine. Therefore, the hydrogenhalides are hydrogen fluoride (HF), hydrogen chloride (HCl), hydrogen bromide (HBr), hydrogen iodide (HI), and hydrogen astatide (HAt).
Under standard conditions, hydrogen fluoride, hydrogen chloride, hydrogen bromide, and hydrogen iodide are gases. They are
Hydrogenhalides are polar molecules due to the significant difference in electronegativity between hydrogen and the halogens.
Industrially, hydrogen halides have numerous applications. Hydrochloric acid, derived from hydrogen chloride, is widely used in
