Ether naming

[Leah M 2C]

Is the -oxy- always placed before the main carbon chain when naming if there is an ether in the molecule? I am confused on the ordering.

[BiancaYugar_1D]

When naming, treat ethers like substituents. That is why the -oxy- appears before the main carbon chain.They do not effect the name of the longest parent chain.

You want to find the longest parent chain without regards to the ether. Then when looking at the ether, you want to see how long the rest of the carbon chain not part of the parent chain is. So if it is attached to a chain of three carbons, it would normally be propyl. However, because it is an ether functional group, it would be propoxy.
