Consider the following reaction mechanism: 1) Initiation Br2 → 2 Br• 2) Propagation (here a cycle of two steps) Br• + H2 → HBr + H• H• + Br2 → HBr + Br• 3) Termination 2 Br• → Br2 This reaction is catalyzed by platinum. Wat causes the bromine to split in the initiation step? Does the platinum influences this or is it just due the weak bonding between Br-Br?

Show the mechanism for the following radical reaction. Classifyeach step as one of the 6 patterns listed on pages 506-507 and label each step as one of the following categories: initiation, propagation, ortermination. (Hint:Each step is going to have two classifications.On of the six patterns and one of the three categories.) (5 pts.) 2. Br2, hv

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.

2. Provide a mechanism for the following remarkable transformation. Use arrows to show the flow of electrons and indicate all formal charges. Note that the rate of this reaction is several thousand times faster than the rate of substitution of hydroxide ion on 3-chloropentane under similar conditions. HINT: The first step of the mechanism is an intramolecular Sn2 reaction in which a ring forms, and the second step involves a subsequent intermolecular Sn2 reaction in which hydroxide ion is the...
