Do the drawings represent constitutional isomers or stereoisomers, or are they just different ways of drawing the same compound? If they are stereoisomers, are they enantiomers or diastereomers? (select) CH3 -Br and Br For -CH3

For the following molecules, draw all possible stereoisomers using line-angle formulas with wedge/dash notation. Label the stereocenters as R or S. Indicate which ones are enantiomers and which ones are diastereomers. (Remember: there are 2 stereoisomers possible for a molecule with n chiral centers) (A) (B) (C) (1 chiral center) Br OH (2 chiral centers) CI OH CH3 (3 chiral centers)

Classify the following pair of compounds as the same compound, enantiomers, diastereomers, constitutional isomers, or not isomeric. Also, select the correct IUPAC name, including the correct (R) or (S) designation, for each. H ÷ ||I The correct IUPAC names are: || J k CI same compound enantiomers diastereomers constitutional isomers not isomeric Compound I: (2R, 3R)-2,3-dichloropentane, Compound II: (2R, 3S)-2,3-dichloropentane Compound I: (2S, 3S)-2,3-dichloropentane, Compound II: (2S, 3S)-2,3-dichloropentane Compound I: (2S, 3R)-2,3-dichloropentane, Compound II: (2S, 3R)-2,3-dichloropentane Compound I: (2R, 3R)-2,3-dichloropentane, Compound II: (2R, 3R)-2,3-dichloropentane

erences) Draw a structural formula of the SR configuration of the compound shown below. CH3 S NR HO Use the wedge/hash bond tools to indicate stereochemistry where it exists. Include H atoms at chiral centers only If a group is achiral, do not use wedged or hashed bonds on it. ood

Does the molecule below exist as a pair of enantiomers? If so, change the bonds to wedges and dashes to reflect R stereochemistry. If the molecule does not exist as a pair of enantiomers, check the box below. Does not exist as enantiomers Cl CH3 OR X

How are they identical, if in the first newman projection CH3 and CH3 are opposite from each other, but then in the second newman projection Br and CH3 are opposite from each other. Wouldnt they be diastereomers since one of the chiral centers changed?
