Review

Aromatics Which radical is more stable? Draw structures to show stabilization.

Map out a synthetic route from benzene and/or ethylene.

Stereochemistry Draw the R and S enantiomers of carvone.

Label each chiral center as R/S. Which are enantiomer? Diastereomers?

Which of these compounds are chiral? 2,2,3,3-tetrabromobutane 2,2-dibromo-3,3-dichlorobutane 2,3-dibromo-2,3-dichlorobutane Draw all stereoisomers of the chiral compound and identify the relationships (enantiomers, diastereomers, meso)

Label each chiral center as R/S. Which are enantiomer? Diastereomers?

Assign R/S to each chiral center. Draw sawhorse projections for I and II. Draw skeletal structures for III and IV showing stereochemistry. Identify the stereochemical relationships.

Map out a synthetic route from ethylene What is the configuration of each chiral center? Is it the only product formed?
