WebOrder of reactivity of alkyl halides The compounds that are also called alkyl halides (haloalkanes) occur when halogen atoms (fluorine, chlorine, bromine, or iodine) are substituted for hydrogen atoms. Haloalkanes (also known as haloalkenes) are organic molecules that contain one or more atoms of halogen (fluorine, chlorine, bromine, or iodine). WebJun 29, 2024 · In S N 2 reactions, primary and secondary alkyl halides and sulfonates are readily displaced by N 3– , resulting in alkyl azides: The usual procedure is to use an azide salt such as NaN 3 or KN 3 with the appropriate alkyl halide in a polar aprotic solvent such as acetonitrile (CH 3 CN) or dimethylsulfoxide ( DMSO ).

The SN2 reaction of an iodide anion with 2-bromobutane. b. The SN1 reaction of a hydroxide anion with 2-bromo-2-methylpropane. Note that the SN2 reaction occurs in one step, while the SN1 reaction occurs in two. Various factors can influence the rates of substitution reactions as well as whether or not the reaction will be SN1 or SN2.
