In organic and organometallic chemistry, an organyl group (commonly denoted by the letter "R") is an organic substituent with one (sometimes more) free valence electron(s) at a carbon atom. ^[1] The term is often used in chemical patent literature to protect claims over a broad scope.^{[ citation needed ]}
