 Alcohols [R-OH]-

In the alcohol functional group, a carbon is single-bonded to an OH group (the OH
group, by itself, is referred to as a hydroxyl).

Except for methanol, all alcohols can be classified as primary, secondary, or tertiary. In
a primary alcohol, the carbon bonded to the OH group is also bonded to only one other
carbon.

In a secondary alcohol and tertiary alcohol, the carbon is bonded to two or three other
carbons, respectively.
