What are alcohols?
Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by a hydroxyl (-OH) group.
OH- is hydroxide, but in organic chemistry side chains end with-yl.
Nomenclature-In the IUPAC system, the name of the alkane chain loses the terminal "e" and adds "ol", e.g. "methanol" and "ethanol".
Primary, secondary, and tertiary alcohols
Primary(1°)- the C-OH is attached to one other carbon (on the end)
Secondary(2°)- the C-OH is attached to two other carbons
Tertiary(3°)- the C-OH is attached to three other carbons
