      You might point out in the theory of oxidation of oils, in development of rancidity in oils, that many methyls accelerate this oxidation of oils. I do not want to burden you with a lecture on chemistry but there are some methyls like iron which has both a valence of two and of three. Another example is cobalt which has a valence of both two and three.

      The southern acetates must be decarboxylated to methyls.
    • 2005, Bruce A. Hathaway, Organic Chemistry the Easy Way, page 38 ↗,
