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Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by a hydroxyl (-OH) group.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
