Etymology

Etymology tree Proto-Indo-European *médʰu Proto-Hellenic *métʰu Ancient Greek μέθυ (méthu) Proto-Indo-European *swel-der.? Ancient Greek ῡ̔́λη (hū́lē)der. German -yl German Methylbor. English methyl Borrowed from German Methyl; compare French méthyle. French chemists Jean-Baptiste Dumas and Eugene Peligot, after determining methanol's chemical structure, introduced "methylene" from the Ancient Greek μέθυ (méthu, “wine”) + ὕλη (húlē, “wood, material”) with the intention of highlighting its origins, "alcohol made from wood (substance)". The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol".

Meanings

1. The univalent hydrocarbon radical, CH₃-, formally derived from methane by the loss of a hydrogen atom; a compound or part of a compound formed by the attachment of such a radical.
   • 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. 1973, Robert E. Cornish, Vitamin and Mineral Deficiencies, page 119:
   • The southern acetates must be decarboxylated to methyls. 2003, Russell Timkovich, 73: The Family of d-Type Hemes: Tetrapyrroles with Unusual Substituents, Karl M. Kadish, Kevin M. Smith, Roger Guilard (editors), The Porphyrin Handbook, Volume 12: The Iron and Cobalt Pigments: Biosynthesis, Structure and Degradation, page 134
   • The most stable form has the groups staggered and the methyls as far from each other as possible (DA^([dihedral angle]) = 180°). 2005, Bruce A. Hathaway, Organic Chemistry the Easy Way, page 38:
