Below the compound on the left is named as an alcohol, but the one on the right is named as a ketone even though both compounds have the seven carbon backbone.
C. E/Z Isomers in Alkenes. In the past, the terms cis and trans have been used to differentiate the isomers; cis to indicate the isomer in which the substituents are on the same side of the double bond, trans when they are on opposite sides.

Nomenclature of ethers. Common names of (symmetrical) ethers add the suffix ether after naming the groups on either side of the oxygen. IUPAC names ethers by taking the more complex alkyl group as the root name, and naming the remaining part as an alkoxy group.
Similar with halides, alcohols can be named based on both substitutive and radicofunctional nomenclatures. In substitutive names, the end of alkanes “ane” is changed to “ol”. In radicofunctional names, the name of the functional group and alcohol are combined. Do not mix, however, two methods.
Naming Ethers IUPAC system • Identify the longest chain and use it as the base name--one exception is if the shorter chain has a name altering functional group • Name the shortest carbon chain with the “oxy” ending & treat it as a substituent • Number location of ether bond on parent chain so that it is as low as possible
Alcohols and Ethers Alcohols: • Alcohols have the general group R-OH. They are polar, moderately water soluble, and moderately acidic. They get higher priority than all hydrocarbons and haloalkanes. Alcohols have lower priority than carbonyl groups. • IUPAC Nomenclature of alcohols follows these steps:
