- Another ether with unlike groups, R—O—R^1 :
In the IUPAC method, the ether name, as shown in the examples, is made up
of two attached alkyl chains to the oxygen. The shorter of the two chains becomes
the first part of the name, with the –ane suffix changed to –oxy and the name of the
longer alkane chain as the suffix. Examples are ethoxyethane and ethoxypropane.
Diethyl ether is commonly referred to as ether and is used as an anesthetic.
Amines and Amino Acids
The group NH 2 − is found in the amide ion and the amino group. Under the proper
conditions, the amide ion can replace a hydrogen in a hydrocarbon compound.
The resulting compound is called an amine. Two examples:
TIP
The amide functional group is
In amides, the NH 2 − group replaces a hydrogen in the carboxyl group. When
naming amides, the -ic of the common name or the -oic of the IUPAC name of the
parent acid is replaced by -amide. For example:
