When reading an infrared (IR) spectrum for an unknown compound, you check for certain functional groups in a certain order. If C=O is absent, you check for alcohols/phenols (-OH), then for amines (N-H), then for ethers (C-O, & the absence of -OH).

Question

When reading an infrared (IR) spectrum for an unknown compound, you check for certain functional groups in a certain order.  If C=O is absent, you check for alcohols/phenols (-OH), then for amines (N-H), then for ethers (C-O, & the absence of -OH).

So, I was wondering: If you look at the structure of eugenol, there is a hydroxyl (-OH) group as well as an ether (R-O-R' = aromatic ring-O-CH3) group.  If an ether only exists when -OH is absent, what do you call the R-O-R' group?
