WebSince IR spectroscopy revealed strong dominance of the P(GPE)-backbone ether oxygens on the Li +-coordination for all dual functional P(GPE)-based electrolytes, lithium transference remains in the range of 0.1 to 0.2, as expected and observed in the case of polyethers. WebMay 4, 2024 · These protons also have two neighbor hydrogens. This makes sense looking at diethyl ether because the two terminal methyl groups are chemically equivalent accounting for the six protons, and each have a neighboring methylene group (-CH2-) with two hydrogens. As a result, all evidence is consistent with isomer 1 being dimethyl ether. …
