WebThe reaction of alkenes with fluorine is too reactive to control, and several competing reactions also occur if fluorine is used. Rearrangement reactions seldom occur when halogens add to alkenes. We recall that water adds to 3,3-dimethyl-1-butene to give a rearranged product as well as the expected product. In contrast, bromine reacts with ... WebExpert Answer.

WebThe 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 the two possible conditions are equivalent to each other. The reaction is a simple addition of the hydrogen bromide. For example, with ethene: WebThis reaction of alkenes happens on the surface of a metal catalyst. The typical catalysts for the alkene hydrogenation are the platinum (Pt), palladium (Pd), and nickel (Ni). Sometimes you’ll see the Pd/C instead of just the pure metal. This is, essentially, the same thing. WebNBS is a source of bromine radical and can be used for free-radical bromination. It is an ideal reagent to use an alkene or alkyne, which has potential to perform an unwanted addition... the psychic development circle with shelley
