WebThe order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive). The reaction is acid catalyzed. Alcohols react with the strongly acidic hydrogen halides HCl, HBr, and HI, but they do not react with nonacidic NaCl, NaBr, or NaI. WebJan 23, 2024 · Step 1: Initiation Once the pre-initiation step involving NBS produces small quantities of Br 2, the bromine molecules are homolytically cleaved by light to produce bromine radicals. Step 2: Propagation One bromine radical produced by homolytic cleavage in the initiation step removes an allylic hydrogen of the alkene molecule. hosting a cooking class https://bridgetrichardson.com
