Question

ChemActivity 10: Oxidation and Radu 11. Draw the major organic product of each of the following reactions (always assume exces | Họcác TC–CH, - Model 5: Reduction of Alkynes H, and Pt or Pd metal will reduce both it bonds of a triple bond; however, careful use of a weaker catalyst (e.g. Lindlar catalyst) will reduce only one bond, giving either a cis or trans alkene. Synthetic Transformations 10.3-10.5: Stereoselective Alkyne Reductions H/Pt or Pd metal 107 R-cac-R HH H2/Ni,B R-C C - R 10.4 Hy/Lindlar Catalyst Lindlar Catalyst Pd that has been "poisoned" (deactivated) by mixing with Caco, quinoline and lead acetate Naº (sodium metal) NH3 m (liquid amonia) 10.5 R-CEC-R NaNH, is commonly confused with the strong base Na Hin which No is acting as a spectator counterton Critical Thinking Questions 12. What evidence in Model 5 tells you it is easier to reduce the first bond of a triple bond than the second a bond of a triple bond? 13. Summarize the differences amone Synth Transf.s 103-10.5 in terms of the products formed
