Halogenation Addition Reaction

Drill: Name: SH I F OH

Addition Reactions Reactions in which more atoms are added to an alkene or alkyne

Halogenation Reactions in which halogens are added to an alkene or alkyne

Halogens Elements from column 7A or column 17 F, Cl, Br, & I

Halogenation C=C + X-Y  -C-C- X Y

Halogenation C=C + IBr  H-C-C-H I Br H H H H H

Predict Product C=C + ICl  H H CH 3 H

Hydrohalogenation Reactions in which hydrogenhalides are added to an alkene or alkyne

Hydrohalogenation C=C + H-X  -C-C- H X

Hydrohalogenation C=C + HCl  H-C-C-H H Cl H H H H H

Markovnikov’s Rule The major products get the “H” on the atom in the DB that already has more “Hs”

Halogen Rxns Predict the products for each of the examples on the board

Substitution Rxns Reactions in which a halogen replaces a hydrogen on an arene

H + X-X X + H-X cat

H + Br-Br Br + H-Br AlCl 3

Other Addition Reactions

Hydrogenation C=C + H 2  H-C-C-H H H H H H Pt

Hydrogenation + H-H Pd
