Halogenation Addition Reaction

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 7 A or column 17 • F, Cl, Br, & I

Halogenation X Y C=C + X-Y -C-C-

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

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

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

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

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

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

Predict & Name Products when HF is added to:

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

Drill: Draw the reactant, then predict & name their products when HCl is added to 2 -methyl-2 -pentene

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 Al. Cl 3
