Classify the 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. The compounds are identical not isomeric constitutional isomers diastereomers enantiomers The correct IUPAC names are: Compound 1: (2R,3R)-2,3-dichlorobutane, Compound 2: (2R,3S)2,3-dichlorobutane Compound 1: (2R,3S)-2,3-dichlorobutane, Compound 2: (2S,3R)-2,3-dichlorobutane Compound 1: (2S,3S)-2,3-dichlorobutane, Compound 2: (2R,3R)-2,3-dichlorobutane Compound 1: (2S,3R)-2,3-dichlorobutane Compound 2: (2R,3S)-2,3-dichlorobutane
