Nomenclature
The IUPAC name of alcohols can derive from the following rules:
# Identify the longest carbon chain, and number each carbon. Name the base alkane according to the
organic nomenclature
In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic compound, organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the ''No ...
rules.
# Identify the hydroxyl group and which carbon it is on. To be alcohol, the -OH must be bonded to a carbon.
# Use the suffix -ol to denote which carbon the alcohol group is on. A three-carbon chain with the -OH on the second carbon would be
propan-2-ol
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor.
Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and c ...
. Note that in some instances, common names are better.
# If the -OH is on the end of the chain, or the carbon chain is only 1 or 2, use no number.
# Use standard Greek prefixes to name molecules with two or more -OH groups (di- for 2, and so on).
