WebJan 23, 2024 · It is a cyclic structure containing 3 oxygen atoms connected in a row, also referred to as a 1,2,3-trioxolane. Molozonide Intermediate This will be your unstable intermediate which will further undergo a rearrangement to form your ozonide. An ozonide is more stable than the molozonide, however it still exhibits a fair amount of instability. WebThe only solution to that is to have two identical ethyl groups either side of the oxygen. The compound is ethoxyethane (diethyl ether), CH 3 CH 2 OCH 2 CH 3. Example 4. Using the simplified table of chemical shifts above, work out the structure of the compound with the following C-13 NMR spectrum.
