CHEM 233 Lecture Notes - Lecture 3: Geranyl Pyrophosphate, Alkene, Ion
Document Summary
Chem 233 worksheet 16: alkene biosynthesis reactions: a biosynthetic sequence is outlined below. Complete the structures in boxes 1-3 by adding necessary features (formal charges, bonds), and draw curved arrows that represent electron movement between each structure. O carbocation intermediate 2 geranyl pyrophosphate (gpp) (e-alkene) On midterms and finals this type of question may be posed as a multiple choice: box 1, structure a, box 1, structure b: Not to be used, copied or revised without explicit permission. Ws16: alkene biosynthesis reactions (no bridge activity for this topic: a biosynthetic sequence is outlined below. Complete the structures in boxes 1-7 by adding necessary features (formal charges, bonds), and draw curved arrows that represent electron movement between each structure. E1 proton loss carbocation intermediate 2 carbocation intermediate 3 verticellene (most stable alkene) 6 addition of proton to form more stable cation (look at box 6!)
