Question

15 multiple choice 2 points what term describes the structural relationship between (2r,3r,4s)-2,3,4-trichloroheptane and (2s,3s,5r)-2,3,5-trichloroheptane? constitutional isomers enantiomers conformers diastereomers

Explanation:

Constitutional isomers have the same molecular formula but different connectivity of atoms. The two compounds have different chlorine - atom positions, which means different connectivity, so they are constitutional isomers. Enantiomers are non - superimposable mirror images, conformers are different spatial arrangements due to single - bond rotation, and diastereomers are stereoisomers that are not enantiomers. Since the connectivity is different here, it is not the latter three cases.

Answer:

A. constitutional isomers
