Document Summary

Electrophilic addition (to an alkene) hbr, hcl, and hi. Br2, cl2 in h2o aromatic rings do not react. Acid catalyzed hydration (only single double bonds reduced) 2 steps: double bond attacks h and electrons from hx bond go to x. Carbocation intermediate is formed (most stable/substituted: x anion attacks positive carbon follows markovnikov (halogen adds to more highly substituted carbon so it can have hydride and methyl shifts) 2 steps: double bond attacks one of the. Br and the 2 electrons from one of the br goes to the other. Bromonium cation intermediate formed: br attacks from other side. 2 steps: double bond attacks the br and the 2 electrons from one of the br goes to the other. Bromonium cation intermediate formed: h2o attacks from other side and makes positive o then water comes in and takes off the positive. 2 steps: double bond attacks the h3o+
