Ether’s general structure looks like this:
The R and R’ are alkyl groups. For example,
Naming Scheme
Naming Ethers is almost the same way that we
name the alkyl group.
We still name the alkyl groups in alphabetical
order and if there is more then one alkyl
group use prefixes like di, tri, tetra, etc.
After all the alkyl groups, the name is
completed by adding ether to the end.
CH3-O-CH2-CH3 This makes: Ethyl Methyl Ether
CH3-O-CH3 This makes: Di Methyl Ether
This makes: Ethyl Propyl Ether
Another Form of Naming
There is an alternate way of naming ethers!
You can add an -oxy- to the prefix of the
smallest hydrocarbon group and make the
larger hydrocarbon group an alkane.
CH3-O-CH2-CH3 This makes: Methoxy Ethane
CH3-O-CH3 This makes: Di Methoxy
This makes: Ethoxy Propane
Reaction Properties
Ethers can be formed through chemical
reactions such as dehydrating alcohols.
An example of this would be:
C2H5 – O – CH2 + H2O
Diethyl Ether
A dehydrating agent such as concentrated
sulfuric acid is used in order for an ether to
form in this reaction.
Everyday Uses
• Ether is included in a sedative that is used
when making people unconscious.
• It works as a good starter fluid in an engine
during cold weather.
• Since ethers are un reactive they are often
found in fats, oils, gums, dyes, and perfumes.
