Epoxide Naming Quiz

What is the historical method of naming epoxides based on?

• The alkene from which they are formed

• The number of carbon atoms in the ring

• The temperature at which they are synthesized

• The type of peroxy acid used

In the IUPAC naming system, what is unique about numbering atoms in an oxirane?

• Numbering is based on the molecular weight

• Carbons are numbered first

How are substituents named in the IUPAC system for oxiranes?

• As substituents off the oxirane

• As part of the main chain

• As separate molecules

• As prefixes to the oxirane name

In the alternative naming method, how is the oxygen in the epoxide viewed?

• As part of the main chain

• As a separate molecule

• As a substituent

• As a prefix to the main chain
