Standard heats reaction values are given for the first three
primary mechanistic steps in the free-radical chlorination of
methane. Explain why the -105kJ/mol overall standard heats of
reaction value for the reaction does not include the standard heats
of reaction value for the initiation step, but instead is the sum
of the standard heats of reaction values for the two propagation
steps.
A. Standard heats of reaction (delta H degree) values are given for the first three primary mechanistic steps...

a) Show the mechanism for the free radical chlorination of
bromopropane. Clearly show the initiation, propagation, and
termination steps.
b) Use the BDEs shown on page 1 to calculate the enthalpy change
for this reaction.
c) Unfortunately, the student’s attempt in question 3 failed,
and he only made traces of 2- chloropropane by using this approach.
What was the major product of the reaction, and explain why it was
formed instead. You may find the BDEs on page 1 to...

III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...
