Write the free radical halogenation mechanism of ethane. Initiation, propagation step 1&2 and termination.
Draw a plausible reaction mechanism for the following radical reaction. Include the initiation, propagation and termination steps. (5 points) 7. Cl hv +C-C +HCI
Draw, for the radical reaction equation below, the following a. Initiation step b. Propagation step c. Termination step d. Possible termination reaction
Select the correct definition for initiation step.
There are three types of
reactions in a free radical reaction. There are initiation
reactions, propagation reactions and termination reactions. Each of
the choices corresponds to one of these.
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...
