Drill: Name the following + 2 isomers FF OH

Name: SH I F O H

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

Drill: Draw the reactants, then predict, draw, & name the products when Cl 2 is added to trans-2-pentene:

CH 3 CH CH 2 CH 3 Cl

CH 3 CH CH 2 CH 3 Cl

CH 3 CH CH 2 CH 3 Cl

CH 3 CH CH 2 CH 3 Cl Pentyl-2,3-dichloride

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”

Predict & Name Products when HF is added to:

Halogen Rxns: Predict the products for each of the examples: 2-methyl-2-butene + HI Propene + HF

Organic HW Draw the reactant, then predict & name the major & minor products when HCl is added to 1- pentene.

Drill: Draw the reactant, then predict & name their products when excess HCl is added to 1-pentyne

Hydration An addition reaction where water is added to an alkene or alkyne

Hydration C=C + H 2 O C-C HOH H+H+

Predict & Name Reactants & Products C=CC=C H H H H + H 2 O HOCl Heat

Ethanol C H OH H H H

Predict & Name Reactants & Products C=CC=C CH 3 H H H + H 2 O acid heat

C H OH Major Product CH 3 H H C H CH 3 H HO H Minor Product

Hydrogenation An addition reaction where hydrogen is added to an alkene or alkyne

Hydrogenation C=C + H 2 H-C-C-H H H H H H cat

Predict the Product + H-H Pd

Name:

Organic HW Draw the reactant, then predict & name the major & minor products when HOH in acid is added to 1-pentene.

Drill: Draw the organic reactants, & draw & name the major products when 3 equivalences of HF is added to penta-1-ene-3-yne

Collect HW

Substitution Reactions Reactions that look as if they should be addition, but substitution occurs instead.

Substitution Rxns Reactions in which a halogen replaces a hydrogen on an arene (benzene ring)

H X-X cat

X + HX

H Br-Br cat

Br + HBr

Hydrocarbon polymerization is the foundation of the plastics industry.

Monomer Molecules that can combine in repeating units creating a polymer

Polymer Large molecules made up of repeating units of single molecules

Naming Polymers The polymer is named after the monomer from which it’s made: polymonomer

Polymerization The act of making polymers out of monomers

Polymerization Reactions

C C C C C C Catalyst is added to start rxn, DB breaks & connects to nearest C & the process continues
