- How to name alcohols and phenols.
In organic chemistry, any alkyl group can be abbreviated as R. An alcohol, in which a hydroxy (-OH) group is attached to a carbon of the alkyl group, can be abbreviated as R-OH.
1. The name of this molecule is ethanol.
What is the name of Molecule A?
2. This molecule is named 2-butanol.
This molecule is named 6-isopropyl-5-nonanol. Number the carbons.
Number the carbons. What is the name of Molecule B?
3. The name of this molecule is 3-propyl-2-octanol. Number the carbons.
4. Number the carbons. What is the name of molecule C?
5. This molecule is named 3-fluorocyclohexanol. Number the carbons.
6. Number the carbons. What is the name of Molecule D?
Molecule D
7. This molecule is named 4-hexen-2-ol. Number the carbons.
8. Number the carbons. What is the name of Molecule E?
9. This molecule is named 2,3-pentanediol.
What is the name of Molecule F?
If a hydroxy (-OH) group is attached to an aromatic ring system, it is called a phenol.
This molecule is named 2-chlorophenol or o-chlorophenol.
1. Name Molecule G using 1) numbers and 2) the o/m/p nomenclature.
2. What additions do we make to our existing naming rules to name alcohols?
3. Write the steps that you use to name an alcohol in order, as instructions for a student who doesn't know how to do it.
4. Draw any alcohol and go through the steps in naming your molecule.
