The first step of the reaction below is formation of a carbocation. Here, the formation of a carbocation via attack of the alkene upon H-Br is shown. (Step 1, arrows A and B).

Double bonds are electron-rich and therefore they react with many electron-deficient species, including acids such as HCl, HBr, and HI. The products of these addition reactions of HX acids …

The simplest type of electrophilic reaction to visualize is the addition of a haloacid such as H B r to an isolated alkene. It is not a biological reaction, but nonetheless can serve as a convenient …

HBr adds to alkenes to create alkyl halides. A good way to think of the reaction is that the pi bond of the alkene acts as a weak nucleophile and reacts with the electrophilic proton of HBr.

The addition reaction of a hydrogen halide molecule, such as HCl or HBr, to an alkene produces an alkyl halide as a product. This process is known as a Hydrohalogenation reaction.

Apr 12, 2013 · Addition of HBr to alkenes in the presence of ROOR (peroxides) and light / heat (of course) results in "anti-Markovnikov" addition of HBr. But why? Read on!

Hydroboration-oxidation is a two step pathway used to produce alcohols. The reaction proceeds in an anti-Markovnikov manner, where the hydrogen (from BH 3 or BHR 2) attaches to the more …

A summary of the Regiochemistry of Alkene Addition Reactions including hydration, hydrohalogentaion (HBr, HCl, HI HBr ROOR), and halogentaion.

The reaction happens at room temperature in the presence of organic peroxides or some oxygen from the air. Alkenes react very slowly with oxygen to produce traces of organic peroxides - so …

If a primary or secondary carbocation can be formed during the reaction, the secondary carbocation will form more readily than the primary carbocation - creating 'major' and 'minor' …
