What is Ether? these compounds are used in dyes, perfumes, oils, waxes and other industrial uses. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Ethers are a class of organic compounds that contain an sp3 hybridized oxygen between two alkyl groups and have the formula R-O-R' General formula CnH2n+2O n : the number of carbon atoms in an ether molecule Naming Ether When no other functional group is present, simple ethers are often given common functional class names. Both alkyl groups attached to the oxygen atom are named as substituents (in alphabetical order) and then the word ether is added. IUPAC nomenclature for ethers should be used for complicated ethers, compounds with more than one ether linkage, and compounds where other functional groups are present with an ether. In these cases, an RO group of the ether is named as an alkoxy substituent. 2-methoxy-2-methylpropane (IUPAC name) Methyl tert-butyl ether MTBE is blended into gasoline to increase knock resistance and reduce unwanted emissions.
