Hydrohalogenation of Alkynes: Electrophilic Addition of HX - JoVE

WebHalohydrogenation Mechanism The double bond steals a hydrogen from H-x, and the electrons from the hydrogen go to the X to form an X with 4 lone pairs (-1 formal charge). The X with a negative formal charge comes back to donate its electrons to the most substituted carbon. WebHydration of alkenes; MECHANISM FOR REACTION OF ALKENES WITH Br 2 / H 2 O: Step 1: Same first step as for the reaction of Br 2 /CH 2 Cl 2. The π electrons act as a nucleophile, attacking the bromine, displacing a bromide ion but forming a cationic cyclic bromonium ion as an intermediate. Step 2: Attack of the nucleophilic water ...
