4.) Cyclic ethers can be named in the IUPAC system using specific IUPAC names for each ring size (oxirane, oxetane, oxolane and oxane for the first 4 cyclic ethers) or they can be named using the epoxy designation to the root name. An additional IUPAC method uses oxa to designate that a carbon in a cycloalkane has been replaced with oxygen. Using the oxacycloalkane naming method, select the correct IUPAC name for the following molecule: 3.) An acceptable IUPAC name...
