Nomenclature
Mechanisms
Reactions
Syntheses
Stereochemistry
Nomenclature:
-be able to name:
alkenes (don’t forget geometric isomerism)
dienes
alkynes
Mechanisms:
-be able to outline all steps in the following mechanisms
using curved arrow formalism and labeling the rate
determining step:
E2
E1
ionic electrophilic addition
free radical electrophilic addition
mechanisms for:
dehydrohalogenation of alkyl halides
dehydration of alcohols
addition of halogens to alkenes
addition of hydrogen halides to alkenes
addition of water/acid to alkenes
addition of halogens/water to alkenes
addition of hydrogen bromide/peroxide to alkenes
Reactions:
-be able to write the structures for the products in the
syntheses and the reactions of
alkenes
dienes
alkynes
Syntheses:
-be able to outline possible laboratory syntheses for
alkenes
dienes
alkynes
Stereochemistry:
-be able to define “stereoselective” and “stereospecific”.
-be able to use Fischer projections to show the
stereochemistry in the products for addition of halogens to
alkenes, hydroxylation with KMnO4 and HCO3H, and E2.
-given the Fischer projections for the products of
stereospecific reactions, be able to show the structures for the
alkene reactants.
-given the structures of the reactants and the products be able
to state whether a reaction is syn- or anti-.
