(a)
Interpretation:
The appropriate curved arrows for each step of a radical chain-reaction mechanism are to be drawn.
Concept introduction:
Due to their high reactivity, free radicals have the probability 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 1) initiation, 2) propagation, and 3) 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.

(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.
