Typically, organic chemists compare the various values from their determination in water, DMSO and the gas phase and use these to predict a compounds reactivity, solubility, and other physical characteristics. Web13 feb. 2024 · A one or two step sequence of simple reactions is not that difficult to deduce. For example, the synthesis of meso-3,4-hexanediol from 3-hexyne can occur by more than one multi-step pathway. One approach would be to reduce the alkyne to cis or trans-3-hexene before undertaking glycol formation. Permanaganate or osmium tetroxide …
