Given the six compounds below. (A through F) answer the following guestions. If there are no possible selections that fit the guestions, indicate "none" as your answer. (Each question is worth 1 point, 6 points total) A 1. Which set(s) is/are enantiomers? 4. Which set(s) is/are the same compounds? 2. Which compound(s) is/are meso compounds? 5. Indicate set(s) is/are constitutional isomers. 3. Which set(s) is/are diastereomers? 6. For the following questions, clearly draw the structures of the expected MAJOR PRODUCT(S). Assume in each case. that the stereochemistry of the reactant is exactly as shown and that no other stereoisomers are present in the starting solution. Also assume that the existing substituents in the reactants DO NOT exert any steric bias or influence facial selectivity of the alkene. Be careful NOT to draw duplicate structures; pointed will be deducted for redundant answers. Once complete with this, indicate in the space provided, which of the following best describes the stereochemical outcome or the stereochemical relationship(s) between the product(s). Options can be used more than once, or not at all. (Each worth 5 points, 10 points total) 1. A pair of optically inactive meso- compounds is produced. II. Four optically active diastereomers are produced. III. Two optically active diastereomers are products. IV. A meso- compound and a diastereomer (as a single enantiomer) are produced. V. A single meso-compound is produced. VI. The major product formed is produced as a racemate. VII. Two sets of optical active enantiomers are produced. a) Options I-VII b) b) Options I-VII 7. Starting with 1-propyne, how could the target compound be synthesized? You can include any reagents and carbon sources you wish, but 1-propyne must be used as the starting material. Write your steps, in numeric order, over/below the reaction arrow. (4 points).
