(a)
Interpretation:
The appropriate curved arrows for each step of a radical chain-reaction mechanism have to be drawn.
Concept introduction:
Due to their high reactivity, free radicals have the potential to be both extremely powerful chemical tools and extremely harmful contaminants. In a chain reaction fashion, the more powerful of free radical species has the natural tendency to occur. This reaction has three separate phases: initiation, propagation, and termination.
The addition of the propagation steps of a chain-reaction mechanism produces the balanced overall reaction.
(b)
Interpretation:
The steps have to be labeled as initiation or propagation in a radical chain-reaction mechanism.
Concept introduction:
Due to their high reactivity, free radicals have the potential to be both extremely powerful chemical tools and extremely harmful contaminants. In a chain reaction fashion, the more powerful of free radical species has the natural tendency to occur. This reaction has three separate phases: initiation, propagation, and termination.
The addition of the propagation steps of a chain-reaction mechanism produces the balanced overall reaction.
(c)
Interpretation:
The balanced net reaction has to be proposed for the radical chain-reaction mechanism.

(d)
Interpretation:
The two plausible termination steps, including curved arrows, have to be proposed for the radical chain-reaction mechanism.
