Industrial, medical
Perfumes/essences
The word alcohol is most commonly referenced to ethanol, the type of alcohol found in alcoholic beverages. The odor in alcohol comes from the fermented sugars in the ethanol.
Methanol and ethanol are the simplest and most commonly used alcohols. Because it is used in alcoholic beverages, ethanol is the most widely used depressant in the world. This led way to the term alcoholism, or addiction to alcohol. Ethanol is also

3. Functional Group: Alcohols
…a hydroxyl group (-OH) bound to a single carbon atom.
General Formula: CnH2n+1OH

4. Identification of Alcohols

5. Naming Alcohol Groups Step 1: Find the alcohol (-OH)
Step 2: Name the parent chain
Step 3: Determine the carbon that the alcohol is coming off of
Step 4: Drop the –e off the parent chain’s name
Step 5: Add –ol to the end of the name
Step 6: The number can be placed before name or between the parent chain and –ol

6. Variations to Alcohol Groups
Can have multiple alcohol groups off of one parent chain
Named –diol, -triol, -tetraol, etc.
Don’t take off the last e on the parent chain.
Ethylene glycol
2,3-butandiol

7. Variations cont… Can have parent chains other than alkanes
Named as alkenol, alkynol, benzenol (phenol), etc.
Can have iso-, sec-, tert- in naming
Names the carbon
that holds the alcohol
t-butanol
phenol

11. Drawing…
Step 1: draw parent chain; number of carbons will be indicated by prefix (i.e. meth, eth, prop…)
Note bond type (i.e. -ene/-yne)
Step 2: find the number carbon the group corresponds to
Step 3: draw the attached group
