Stabilization by hyperconjugation. The sequence of radical stability may be explained by the differing amounts of hyperconjugation. The more alkyl substituents a radical carbon atom possesses, the more stabilized it becomes from hyperconjugation.

Radical Chain-Growth Polymerization. Virtually all of the monomers described above are subject to radical polymerization. Since this can be initiated by traces of oxygen or other minor impurities, pure samples of these compounds are often “stabilized” by small amounts of radical inhibitors to avoid unwanted reaction.

Free Radical Reactions in Synthetic Organic Chemistry
At least in the context of physical organic chemistry, it seems desirable to cease using the adjective ‘ free ‘ in the general name of this type of chemical species and molecular entity, so that the term ‘ free radical ‘ may in future be restricted to those radicals which do not form parts of radical pairs. Depending upon the core atom that possesses the unpaired electron, the radicals can be

In recent years, there has been a great deal of attention toward the field of free radical chemistry. Free radicals reactive oxygen species and reactive nitrogen species are generated by our body by various endogenous systems, exposure to different physiochemical conditions or pathological states.
In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valence electrons or an open electron shell, and therefore …
To the extent that the organic radical becomes free, it should be trappable by an appropriate scavenger. As also shown in Scheme 11, 95% of the cycloheptyl radicals generated in the treatment of cycloheptyl bromide with magnesium metal in ether solvent are trapped by TEMPO as the radical coupling product.

The whole point of this article is to say that yes. such species do exist. the father of free radical chemistry. or Moses Gomberg. and they are called “free radicals” [the etymology of this term is interesting.We would expect such a species to be highly reactive. but if you’re curious you could try reading about EPR.
An atom or molecule that contains one or more unpaired electrons is called a free radical (or simply a radical). Needless to say, any molecule that has an odd number of electrons is by definition a free radical.

In chemistry, a radical is an atom, molecule, or ion that has an unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive.

Single-electron transfer from PFRs to H 2 O 2 was a possible mechanism for H 2 O 2 activation by biochars, which was supported by free radical quenching studies. The findings of this study provide a new pathway for biochar implication and insight into the mechanism of H 2 O 2 activation by carbonaceous materials (e.g., activated carbon and graphite).
