UNIT 2
MODULE 1: THE CHEMISTRY OF CARBON COMPOUNDS (cont’d)

SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

2. Functional Group Analysis, Reactions and Mechanisms

Students should be able to:

2.1. identify homologous series Include general formulae.
of organic/carbon
compounds;

2.2. describe selected chemical Halogenation, cracking and
reactions of alkanes; combustion.
Equations required.

2.3. explain the steps involved Steps should include
in the mechanism of free initiation, propagation and
radical substitution; termination. For example,
methane and chlorine,
homolytic fission.
Include movement of
electrons to be indicated
by curved arrows and fish
hook notations.

2.4. describe selected chemical
C C
reactions of alkenes;
Alkenes with Br 2 (l),

Br 2(aq) , (addition reaction)
+
Cold - KMnO4(aq)/H (aq)
(oxidation and diol
formation),
+
Hot - KMnO4(aq)/H (aq)
(cleavage).
Hydrogen halides.
(Markovnikov rule for
addition to asymmetric
alkenes).
Include catalytic
hydrogenation of fats to
produce trans–fats which
are harmful, for example,
margarine.

Equations for reactions of
alkenes with KMnO4(aq)
+
/H (aq) are not required.
