Alcohols
Alcohols are a homologous Structure of
series of organic compounds alcohols
that have the general formula
CnH2n+1OH. They have the
functional group -OH, which is
also called the hydroxyl group.
Naming alcohols
The name of alcohols end with
–ol.
Name n Molecular
formula
Properties of
Methanol 1 CH3OH
alcohols
Ethanol 2 C2H5OH • Alcohols are soluble in
water but their solubility
Propanol 3 C3H7OH decreases as the
molecular size increases.
Butanol 4 C4H9OH • The first four alcohols
are liquid at room
temperature and
pressure
• Alcohols are neutral. (not
alkaline)
