Hint:In order to name epoxides and ethers firstly the classify the compounds, a compound in which two carbon atoms are connected to an oxygen atom likewise epoxides are the three membered, cyclic compounds. Also all ethers will also have a similar common name, which is often used as with the IUPAC name. If we want to acquire the common name, we have to name the two groups flanking the atom in an alphabetized form and the word "ether" is added along with that.
Complete answer:
There are several ways of naming epoxides and ethers. In which epoxides is classified by two ways naming:
Substitutive names:These compounds we named as an alkane with an alkoxy alkane. Example is
Functional class names: is named with the names of and in alphabetical order, followed by the class name "ether". Example is ethyl isopropyl ether.
Also ethers is naming classified by-
Substitutive names:The compound is named as an alkene with an epoxy substituent. Example,
Functional class names:The compound is named as an epoxide of the corresponding alkene. Example, is also named as
The Hantzsch Widman name:Here the ring we had named as a cyclopropane in which the atom replaces a group indicated by the prefix "oxa" with the "a" which is being dropped when followed by a vowel. The three membered saturated ring is indicated by the prefix "ir" followed by the suffix "ane".
Therefore, is called ethyloxirane. The O atom is automatically number , so the ethyl group is on . We have no locating number is necessary here, because there is no such compound as
Oxide of the Correspondent alkene:Examples are ethylene oxide and propylene oxide. The first three methods are accepted by IUPAC.
The fourth is used only for simple alkenes such as ethylene, propylene, and butylene.
Note:Also note that thiols are compounds that are structurally identical to alcohols except that they replace the oxygen atom in the hydroxyl group with a sulfur atom. Likewise, sulfides are structurally identical to ethers, but they replace the oxygen atom with a sulfur atom, as shown below.
