This functional group shows up in so many alcohols it has come to be known as the alcohol group. It's really called: Hydroxyl Functional Group. Todd Helmenstine, sciencenotes.org hydroxyl ho group oxyhol carboxyl 2. This functional group is the general version of the previous hydroxyl group. Ether Functional Group. Todd Helmenstine, sciencenotes.org oxyhol roxy ether ester 3. This functional group looks like it has oxygen on a pedestal. Ketone Functional Group. Todd Helmenstine, sciencenotes.org ether ketone ester carboxyl 4. Replace the oxygen of the hydroxyl group with sulfur and you get this functional group. Thiol Functional Group. Todd Helmenstine, sciencenotes.org sulfoxyl sulfa librarian (-SH) thiol 5. This functional group is derived from ammonia where one or more of the hydrogen atoms are replaced. Amine Functional Group. Todd Helmenstine, sciencenotes.org amine amide nitrile nitro 6. A carbon, nitrogen and an oxygen gather together. This party is known as: Amide Functional Group. Todd Helmenstine, sciencenotes.org carnox amino acid amide nitroxyl 7. This variation of the ketone group is called: Aldehyde Functional Group. Todd Helmenstine, sciencenotes.org aldehyde anhydride hydroxyl carboxol 8. This structure is sometimes known as the COOH group or: Carboxyl Functional Group. Todd Helmenstine, sciencenotes.org carbonyl carboxyl acetyl hydroxyl 9. This functional group is found in many fats and natural oils. This group is: Ester Functional Group. Todd Helmenstine, sciencenotes.org ether ester alkoxy dioxyl 10. This functional group comes with its own ring. This ringed group is called: Phenyl Group. Todd Helmenstine, sciencenotes.org benzyl carboring hexyl phenyl Organic Functional Group Quiz You got: % Correct. Functional Group Go-Getter Peter Dazeley / Getty Images A functional group is a set of atoms that act together to participate in chemical reactions.
