NettetHydrogen iodide (H I) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid.Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas.They are interconvertible. NettetThe iodine will react with those sites and the magnesium iodide formed will dissolve away and that consequently exposes more Mg (O) on the surface. It will reach a point where the alkyl halide you're using can take over and accelerate the process. Iodine “activates” magnesium so it can form a Grignard reagens.
