You should be able to: 

  1. * Nomenclature: Given a structure write the IUPAC name, or given an IUPAC or common name draw the structure, for any alkyne or alkadiene. [9.2]
  2. * Stereochemistry:
    1. * Recognize and draw stereoisomers (enantiomers, diastereomers, and meso compounds) using Fischer, Newman, sawhorse, wedge-and-dash, and cyclohexane chair stereo projections. [7.1-7.5, 7.7]
    2. Assign R or S absolute configurations to stereogenic centers. [7.6]
    3. * Predict the stereochemical outcome of chemical reactions. [7.9, 7.13]
  3. * Mechanisms:
    1. * Predict when SN1, SN2, E1, or E2 mechanisms will occur in a chemical reaction and predict the structures of the products, including stereochemistry. [8.4-8.14]
    2. Be familiar with stereochemical consequences of applying particular mechanisms. [7.13, 8.8]
  4. *Reactions: Carry out single-step reactions and multistep syntheses using:
    1. * Nucleophilic substitution [8.1, 8.15]
    2. * Preparation of alkynes
      1. alkylation of acetylene [9.7]
      2. elimination of dihalides [9.8]
    3. * Reactions of alkynes
      1. hydrogenation [9.10]
      2. reduction [9.11]
      3. addition of hydrogen halides [9.12]
      4. hydration [9.13]
      5. addition of halogens [9.14]
      6. ozonolysis [9.15]
