5. The oil, caryophyllene, also a terpene, is a natural constituent of cloves. On treatment with sulfuric acid, it isomerizes to a substance called clovene. Provide an arrow pushing mechanism for this conversion, that begins with protonation of the upper double bond to give the most stable carbocation. H,SO,,H,O Caryophyllene Clovene

The enzyme GGPPS catalyzes three reactions to take DMAPP and isopentenyl diphosphate to form the final C20 product. From what you know now about enzymes, which statement is incorrect? A) The tertiary structure of the active site of GGPPS seems to fit isoprenoid products up to C20. B) The inhibitor zaragozic acid C, or at least a part of it must be similar to a C15 isoprenoid to "fool" the enzyme and stop the modification of farnesyl diphosphate. C) Zaragozic...

What solvent would be best to carry out the substitution of the benzyl iodide shown below and why? H2N solvent at 70 °C 1.0 equivalents Methanol, because this reaction performs best with a polar protic solvent to solvate charged intermediates. DMSO, because this reaction performs best with a polar aprotic solvent which will dissolve the nucleophile without hydrogen bonding. O Hexanes, because this reaction performs best with a nonpolar solvent to...
What is the best explanation for why graphite is slippery whereas diamond is not? a. Because electrons in graphite are delocalized, but the electrons in diamond are not. b.
