A complete mechanism for the given reaction is to be provided. Concept introduction: Under acidic conditions, an ether is protonated, converting the oxygen into a better leaving group and the adjacent carbon into an electrophile. The oxygen is bonded to a primary carbon. Therefore, its substitution will occur via the S N 2 mechanism. Once the ether oxygen is protonated and converted to a better leaving group, the nucleophile ethanol will attack the adjacent carbon, opening the ring. A second substitution can take place, replacing the − OH group at the other end of the opened chain by a second ethoxide to give a disubstituted product.
