Example Sentences
- "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."
- "The most stable form has the groups staggered and the methyls as far from each other as possible (DA^([dihedral angle]) = 180°)."
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".
