There are 3 distinct ways to name cyclic ethers. But before we get into them, let’s first specifically define what an epoxide is.
Name the ring as a cycloalkane, adding the prefix oxa- and location if necessary.
Name as a typical alkane, and then include epoxy as a di-located substituent.
Name as an imaginary alkene, then follow with the word oxide.
Concept: How to name epoxides using the oxide convention.3m
Note: I forgot to address in the videos that both of these would be trans due to the alkyl groups facing opposite sides of the ring.
Example: Provide ALL the names applicable for the following molecule.3m
Example: Provide ALL the names applicable for the following molecule.8m
