UNIT 8
LEARNING OBJECTIVES
The learner will
1. explain why
the addition of a substance to a double bond is called an electrophilic
addition reaction.
2. know the different reactions of the
alkenes and their mechanism including: addition of hydrogen, addition of
halogen, addition of hydrogen halide, addition of sulfuric acid, addition of
water, halohydrin formation, alkylation, oxymercuration-demercuration, hydroboration-oxidation,
hydroxylation, epoxidation and ozonolysis.
3. explain
completely including the reaction, conditions and mechanism for the
hydrogenation of an alkene.
4. explain the
application of the Markovnikov's rule in the addition of hydrogen halide
compounds to an unsaturated alkene.
5. explain the
application of the "anti" Markovnikov's rule in the addition of
hydrogen halides in the presence of peroxides.
6. write the
mechanism for ozonolysis of an alkene.
9. give the
mechanisms for addition of OH group or
groups to alkenes.
10. know the
mechanism of oxidation of alkenes by potassium permanganate.
11. know the
methods for determining the presence of a double bond in alkenes.
