WebJan 23, 2024 · Alkenes react with hydrogen bromide in the cold. The double bond breaks and a hydrogen atom ends up attached to one of the carbons and a bromine atom to the other. In the case of ethene, bromoethane is formed. (1) CH 2 = CH 2 + HBr → CH 3 CH … The mechanism for the reaction between ethene and sulfuric acid. The hydrogen … WebIn this example, HCl adds to but-1-ene to form racemic 2-chlorobutane: The mechanism begins with an electrophilic addition elementary step, where the alkene forms a new sigma bond to the electrophilic H, and breaks the H-Cl bond displacing Cl¯. The second elementary step is a coordination step, where the chloride ion attacks the carbocation to ...

They are … WebThe reaction of 2-butene with HCl has a greater free energy of activation. This is because the more substituted alkene is lower in energy and more stable (less reactive). Since both 1- and 2-butene pass through the same secondary carbocation intermediate, we can assume that 2-butene will have a higher activation energy for reaction. OH H2SO4 O ...
