1. Starter questions Name this molecule: Draw these molecules:
3-ethyloctane
1,4-dibromohexane
2,3,4-trimethylheptane
3,4-diethyl-3,4,5-trimethyldecane

2. Naming compounds with functional groups
L.O.:
Understand and use the IUPAC rules of nomenclature for naming compounds with functional groups.

3. Prep work: read pages
Specially pay attention to:
How to calculate empirical and molecular formulae
Difference between molecular and displayed formula.

4. IUPAC International Union of Pure and Applied Chemistry.

5. Pentan-3-ol

6. Adding oxygen 1: Alcohols
The OH group is called an alcohol
We either add a “–ol” to the end or an “hydroxy-” to the beginning for the name
Draw these alcohols
Methan-1-ol
Butan-2,3-diol
3-ethyl-2-methylheptan-1,2,3,4,5-pentol

7. Adding suffixes starting with a vowel
We drop the ‘e’ after the alkane, so the alcohol of propane becomes propan-1-ol

8. Butanal

9. Adding oxygen 2: Aldehydes
Most famous is formaldehyde, CH2O, used to preserve dead tissue
All have a doubly bonded oxygen, the “=O”, group at the end of the alkyl chain
End with the suffix “-al”
E.g.
Propanal
1,1-dibromobutan-4-al
3-ethylpentan-1-al

10. Adding oxygen 3: Ketones
Most famous is acetone, C3H6O used in nail varnish remover
The “=O” group is added to a carbon within the chain, not at the end as in aldehydes
Simply add a “-one” suffix to the name
e.g.
Propan-2-one
3-bromo-2-methylheptan-4-one
2,3-diiodo-2-methylhexan-4,5-dione

11. Halogenoalkenes
-F, -Cl, -Br, -I Prefix: Fluoro- Chloro- Bromo- Iodo- Example: 1-chloropropane

12. 1- Chloropropane

13. 2-Bromo-1-chlorobutane

14. 1,1,2,2-Tetrachloroethane

18. ACIDS

19. More than one functional group or side chain
2-bromo-1-iodobutane
2-bromo-1-iodopo
