This is the right answer

Radicals, which usually cannot be isolated, appear in small concentrations at intermediate stages of radical reactions.

Because of an unpaired electron, radicals are highly reactive and unstable molecules.

Radicals can, oftentimes, easily be isolated and appear in high concentrations in radical reactions.

Radical reactions are often chain reactions.

The intermediate stages are recovered only once, while the starting products are converted into the product in a continous cyclic process.

The chain reaction is a linear process, in which the radicals are converted into the starting products, while the intermediate stages are consecutively formed.

Single intermediate stages are repeatedly recovered until all product molecules have been converted into the starting products by a cyclic process.

Certain intermediate stages are repeatedly recovered, while the starting product molecules are converted into the product molecules by a cyclic process.
