Step 1: The pi electrons of the alkene attack a hydrogen of HBr resulting in the formation of a carbocation and a bromide ion. The carbocation is a high energy intermediate making this the rate determining step (slow step) of the reaction. Step 2: When there is no favorable rearrangement the bromide ion carries out ...
WebBy definition, alkenes are hydrocarbons with one or more carbon–carbon double bonds (R2C=CR2), while alkynes are hydrocarbons with one or more carbon-carbon triple bonds (R–C≡C–R). Collectively, they are called …
WebReaction 1: Addition of hydrogen halide to an alkyne Summary: Reactivity order of hydrogen halides: HI > HBr > HCl > HF. Follows Markovnikov’s rule: Hydrogen adds to the carbon with the greatest number of hydrogens, the halogen adds to the carbon with fewer hydrogens.
