WitrynaIn organic synthesis this may involve the addition of molecular halogens: chlorine, bromine, iodine, or fluorine (Cl2, Br 2, I 2, or F 2) or hydrohalogenation using: hydrogen chloride, hydrogen bromide, hydrogen iodide, or hydrogen fluoride (HCl, HBr, HI, or HF) to carbon-carbon double bonds.

WitrynaThe order of reactivity of the halogens in haloalkanes is I > Br > CI > > F. Organofluorides are so unreactive that they are never used to prepare Grignard reagents. Organohalogen compounds containing bromine and chlorine are readily available, and are commonly used to prepare Grignard reagents. elanco wormerWitrynaHalogenation Reagents.
