 Alkoxy radical

An alkoxy radical has the form $\mathrm{RO}\cdot$, with an unpaired electron associated with oxygen. It differs from the closed-shell alkoxide anion $\mathrm{R}{\mathrm{O}}^{-}$.

Hydrogen abstraction and carbon-carbon bond fragmentation are possible reaction pathways depending on the attached group and environment. Distinguishing radical character from negative charge is essential when interpreting how such an oxygen-centered species reacts.
