What you learn in Theory:
Alcohols and phenols may be classified as mono–, di–, tri- or polyhydric compounds depending on whether they contain one, two, three or many hydroxyl groups respectively.
What you learn in Practice:
In the class of alcohols, the –OH group is attached to an sp3 hybridised carbon atom of an alkyl group.
