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. compound 1 has two chiral carbons. carbon 1 has a chlorine on the upper left and is bonded to carbon 2 on the upper right. pointing down, there is a wedge bond to methyl and a dashed bond to hydrogen. carbon 2 is bonded to a hydrogen on the lower right and to carbon 1 on the lower left. pointing up, there is a wedge bond to methyl and a dashed bond to chlorine. compound 2 has two chiral carbons. carbon 1 has a bond to hydrogen on the upper left and is bonded to carbon 2 on the upper right. pointing down, there is a wedge bond to chlorine and a dashed bond to methyl. carbon 2 is bonded to a methyl group on the lower right and to carbon 1 on the lower left. pointing up, there is a wedge bond to chlorine and a dashed bond to hydrogen. the compounds are constitutional isomers not isomeric diastereomers identical enantiomers the correct iupac names are: compound 1: (2s,3s)‑2,3‑dichlorobutane, compound 2: (2s,3s)‑2,3‑dichlorobutane compound 1: (2r,3r)‑2,3‑dichlorobutane, compound 2: (2r,3r)‑2,3‑dichlorobutane compound 1: (2s,3s)‑2,3‑dichlorobutane, compound 2: (2r,3r)‑2,3‑dichlorobutane, compound 1: (2r,3s)‑2,3‑dichlorobutane, compound 2: (2r,3s)‑2,3‑dichlorobutane,
