Web9.7: Electrophilic Addition to Alkynes: Hydrohalogenation. Electrophilic addition of hydrogen halides, HX (X = Cl, Br or I) to alkenes forms alkyl halides as per Markovnikov's rule, where the hydrogen gets added to the less substituted carbon of the double bond. Hydrohalogenation of alkynes takes place in a similar manner, with the first ... WebHydrogen halides provide both a electrophile (proton) and a nucleophile (halide). First, the electrophile will attack the double bond and take up a set of π electrons, attaching it to …

Alkynes have a very similar reactivity to alkenes. They undergo the electrophilic additions like halogenation and hydrohalogenation. They can also be reduced with the aid of a heterogeneous catalyst or oxidized via several techniques. Alkynes do, however, have a number of unique reactions that you’re ... fatc with digital display
