Concept explainers
(a)
Interpretation: The given pair of compounds, A and B is to be classified as identical molecules, enantiomers, or diastereomers.
Concept introduction: Enantiomers of a compound are the stereoisomers which are non-super imposable mirror images. A carbon atom bonded to four different groups is known as a chiral carbon. A compound which has a chiral carbon can be resolved into enantiomers.
Diastereomers of a compound are the stereoisomers which are non-super imposable non mirror images. On the other hand, identical molecules have superimposable mirror images and similar chemical and physical properties. They possess same
(b)
