Question

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. The correct IUPAC names are: Compound I: (3S, 4S)-3, 4-dimethylheptane, Compound II: (3R, 4S)-3, 4-dimethylheptane Compound I: (3R, 4S)-3, 4-dimethylheptane, Compound II: (3S, 4S)-3, 4-dimethylheptane Compound I: (3R, 4S)-3, 4-dimethylheptane, Compound II: (3S, 4R)-3, 4-dimethylheptane Compound I: (3S, 4S)-3, 4-dimethylheptane, Compound II: (3S, 4S)-3, 4-dimethylheptane

Explanation / Answer

IUPAC names selected option is correct

Compound I is ( 3R,4S)   while compound II is ( 3S,4S)

The given two compounds are   diasteromers

( diatermoers are stereo isomers which are partial super imposable ( both have 4S) and partial non super imposable )
