Epoxide Nomenclature

There are 3 distinct ways to name cyclic ethers. But before we get into them, let’s first specifically define what an epoxide is.  

Cycloalkane Convention

Name the ring as a cycloalkane, adding the prefix oxa- and location if necessary.

Epoxy Convention

Name as a typical alkane, and then include epoxy as a di-located substituent. 

Oxide Convention

Name as an imaginary alkene, then follow with the word oxide

Concept: How to name epoxides using the oxide convention.
