WebDec 10, 2024 · (In cyclic alcohols, the carbon atom bearing the OH group is designated C1, but the 1 is not used in the name.) Substituents are named and numbered as in alkanes. If more than one OH group appears in the same molecule (polyhydroxy alcohols), suffixes such as - diol and - triol are used.
