WebRecall that addition of HBr to alkenes is a regioselective reaction in which the bromine is directed to the carbon of a double bond with the greater number of alkyl groups (Sec. 4.7A). For example, 1-pentene reacts with HBr to give almost exclusively 2-bromopentane: (5.41) For many years, results such as this were at times difficult to reproduce.

WebHowever, there are two specific reactions among alkynes where anti-Markovnikov reactions take place: the radical addition of HBr and hydroboration-oxidation reactions. For alkynes, … WebStep 1: First, electron deficiency part of halogen acid (H atom) , is added to the π bond of alkene. Meanwhile, H-Br bond is broken and both electrons in the bond, gets displaced towards bromine atom. This reaction slowly occurs. Step …

WebDec 2, 2024 · What you should be looking at is the stability of the carbocation intermediate formed when the strong acid H B r protonates the alkene. This stability is more sensitive … WebThis is due to the abstraction of a hydrogen atom by the alkene from the acid (HX) to form the most stable carbocation (relative stability: 3°>2°>1° >methyl), as well as generating a halogen anion . A simple example of a hydrochlorination is that of indene with hydrogen chloride gas (no solvent): [4]
