As with other types of organic compounds, alcohols are named by both formal and common systems. The most generally applicable system is that adopted at a meeting of the International Union of Pure and Applied Chemistry (IUPAC) in Paris in 1957.
A one carbon alcohol is methanol (methyl alcohol), two carbons is ethanol (ethyl alcohol), three carbons is propanol. A partcicular arrangement of those three carbons gives you isopropyl alcohol or isopropanol. Ehtyl alcohol is the stuff you buy in the liquor store.eport Abuse. denatured alcohol is ethyl with added stuff to make it undrinkable. It is used as a solvent. ethyl is C2H5OH propyl and isopropyl are C3H7OH propyl and isopropyl have the same basic formula, but the molecules look different.
