Web2 days ago · One of the main problems in chemotherapy using platinum drugs as anticancer agents is the resistance phenomenon. Synthesizing and evaluating valid alternative compounds is challenging. This review focuses on the last two years of progress in the studies of platinum (II)- and platinum (IV)-based anticancer complexes. In particular, the … WebJan 23, 2024 · One important use of the cis conformation of a conjugated diene is that it is used diels-alder cycloaddition reactions. Even though the trans conformation is more stable the cis conformation is used because of the molecule's ability to interconvert and rotate about the single bond. Molecular Orbitals
WebIn "The Nuclear Tourist," Johnson explains "the specter of nuclear meltdown." The word specter contains the Latin root -spec., meaning "to see" or "to look." WebJun 21, 2024 · Cis and trans stereoisomers of 1,2-dimethylcyclohexane In cis -1,2-dimethylcyclohexane, both chair conformations have one methyl group equatorial and one methyl group axial. As previously discussed, the axial methyl group creates 7.6 kJ/mol of steric strain due to 1,3-diaxial interactions.
WebSteam distillation allows eugenol and water to combine its vapor pressure. The combined vapor pressure leads to a lower boiling point than both eugenol and water alone. The combined vapor pressure reaches the atmospheric pressure quicker. P total=P1+P2+P3 IR spectrum of eugenol. -OH peak is 3500 -C=C at 1610, 1640 -C-O at 1270 cis-trans-Isomerie tritt auf, wenn beide Atome einer Doppelbindung unterschiedliche Substituenten tragen. Die Referenzebene ist in diesem Fall diejenige Ebene, die die Achse der Doppelbindung enthält und zugleich senkrecht auf jener Ebene steht, in der die σ-Bindungen zu den Substituenten liegen. Ein Beispiel für cis-trans-Isomerie ist das Isomerenpaar cis-Butendisäure (Maleinsäure) und tra…
