Task: Text Categorization
Input (English): A proton-ionizable group is found in the "lariat" form of these compounds, which are NOT cleaved into carboxylic acids during a positive result in the Zeisel method. Lithium-containing compounds are used to transform them in the 1,2-Wittig rearrangement, and they easily undergo oxidation to form peroxides. An acid catalyst and two primary alcohols are needed in a condensation reaction to create these compounds while the most famous way to produce them involves nucleophilic substitution of an alkyl halide by an alkoxide. For 10 points, name this class of molecules with formula R-O-R that are produced in a reaction named for Williamson.
Output (English): Science
