ETHERS

Ethers are compounds having two alkyl or aryl groups bonded to an oxygen atom, as in the formula R1-O-R2. The ether functional group does not have a characteristic IUPAC nomenclature suffix, so it is necessary to designate it as a substituent. To do so the common alkoxy substituents are given names derived from their alkyl component CH3-

M.RULE

Ethers can be named by naming each of the two carbon groups as a separate word followed by a space and the word ether. The -OR group can also be named as a subtitle to using the group name, alkox
