A student performed a reaction using 2-methoxyethanol as solvent under acid catalyst. When the solvent was redistilled, a higher boiling fraction (bp=162 °C) was also recovered. The mass spectrum showed a molecular ion at 134 m/z. The H nmr spectrum showed a triplet integrating for 2 at 3.55 ppm, a second triplet integrating for 2 at 3.65 ppm, and a singlet integrating for 3 at 3.4 ppm. Give the structure of the newly formed material that is consistent with this data.
