Radical chain reactions involve three main steps: initiation, propagation, and termination. Initiation is the first step and generates radicals. Propagation sustains the chain reaction by transferring radicals. Termination is the final step where radicals are used up and the chain ends. The document matches terms related to these three steps in a polymerization chain reaction.

1. Match the following chain reaction /polymerization terms Note: There are extra incorrect
answers, so be carefull Propagation Chain radical Mutual termination Termination Initiation
Disproportionation initiation Monomer radical Catalyst The term for the last step in a chain
reaction that results in using up radicals. The term for the step in a chain reaction that sustains
the chain The term for the first step in a chain reaction Average chain length
Solution
Radical chain reaction has 3 steps: chain initiation, propagation and termination.
a) Last step in the chain that results in using up radicals is called termination
b) Step that susustains the chain reaction is called propagation.
c) The first step in the chain reaction is initiation.
Initiation step involves the generation of radicals.
