Organic substituent with one or more free valences at a carbon atom
In organic and organometallic chemistry, an organyl group is an organic substituent with one (sometimes more) free valence(-s) at a carbon atom.[1] The term is often used in chemical patent literature to protect claims over a broad scope.[citation needed]
