2. In common radicofunctional nomenclature alcohols are called alkyl alcohols such
   as methyl alcohol, ethyl alcohol, isopropyl alcohol, and so on.

11.1B NOMENCLATURE OF ETHERS

1. Simple ethers are frequently given common radicofunctional names.

2. IUPAC substitutive names are used for more complicated ethers and for
   compounds with more than one ether linkage.
