Abstract: A homologous series of (3-alkoxymethyl-4-hydroxyphenyl)ethanones was prepared by the reaction of (3-chloromethyl-4-hydroxyphenyl)ethanone with the different alcohols in the presence of sodium hydrogen carbonate. The confirmation of structures was achieved by interpretation of IR, UV, and ¹H NMR spectra. Molecular modeling methods were used to establish conformations with global and local energetic minima. It was found that energetically the most stable conformations involved hydrogen bond formation between the hydrogen of phenolic group and the oxygen of alkoxyl group. Enthalpy values of hydrogen bonds of selected compounds were 24.86—30.51 kJ mol⁻¹ and their distances were in the range 0.282—0.293 nm.
