Alkene Mechanisms Cheat Sheet - Variation of rates when you change the halogen. Syn addition (added to same side) can occur with d2 or t2 (deuterium or tritium, isotopes of hydrogen) ________________________________________________________________________. Web all alkenes undergo addition reactions with the hydrogen halides. A hydrogen atom joins to one of the carbon atoms originally in the double bond, and a halogen atom to the other. Reaction rates increase in the order hf < hcl <hbr < hi. Summary of all alkene reactions (with example/important notes) 1.) catalytic hydrogenation.
