They are further classified as follows:
Primary, secondary and tertiary alcohols: In these three types of
alcohols, the –OH group is attached to primary, secondary and
tertiary carbon atom, respectively as depicted below:
Allylic alcohols: In these alcohols, the —OH group is attached to
a sp
3 hybridised carbon adjacent to the carbon-carbon double
bond, that is to an allylic carbon For example
Benzylic alcohols: In these alcohols, the —OH group is attached
to a sp
3—hybridised carbon atom next to an aromatic ring For
example The classification of compounds makes their study systematic and
hence simpler
