    The substituent name for the \(RO-\) function is alkoxy, and it is correct to name \(R-O-R'\) compounds as alkoxy derivatives of hydrocarbons:

    Top left: C H 3 single bond O single bond C H 2 C H 2 C H 3. Labeled 1-methoxypropane. Bottom left: C H 3 C H 2 O single bond C H double bond C H 2. Labeled ethoxyethene. Right: benzene ring with O C H 3 substituents on carbons 1, 3 and 5. Labeled 1,3,5-trimethyoxybenzene.

    In the common nomenclature for ethers, each of the \(R\) groups in \(R-O-R'\) is named as a separate word, except when the groups are identical, in which case the prefix di or bis may be used (di is used for simple groups, bis for substituted groups):

    Left: C H 3 C H 2 O C H 3. Labeled ethyl methyl ether. Middle: Oxygen singly bonded to two benzene rings. Labeled diphenyl ether. Right: C L C H 2 O C H 2 C L. Labeled bis(chloromethyl) ether.
