3. Functional Groups with Prefix Only (ii)
Examination of the following line diagram for a representative ether:
the longer of the two chains forms the root name, alkane.
Examine the following :
When more substituents are present, the alkoxy substituent takes up its alphabetical position in the list of prefixes:
A note on common names for ethers.
An older but still acceptable naming system for the smaller ethers was to use the generic name: alkyl alkyl ether (note the spaces between the words!) , where the alkyls represent the two carbon chains, and the ether the disubstituted-oxygen family.
Examples of this method for compounds previously named are:
methyl ethyl ether,
methyl n-propyl ether,
methyl isopropyl ether,
