Does resonance help radical stability?
Recall that radical stability follows the trend:
From left to right we have a primary (
Radicals have an
Consider this allylic radical
Using half arrows to denote electron movement, resonance of an allylic radical can be shown. Recall that resonance shows how charges can be delocalized among multiple atoms.
The same can be seen for a benzylic radical
Remember: The more resonance forms a structure has, the more stable it is
