(a)
Interpretation:
The blank in the given sentence should be filled by suitable word.
Concept introduction:
Diastereomers are stereoisomers which are neither mirror images nor identical. If two stereoisomers are not enantiomers, then they are Diastereomers.
The pair of Enantiomers has opposite configurations for each asymmetric centers in a compound.
(b)
Interpretation:
The blank in the given sentence should be filled by suitable word.
Concept introduction:
Diastereomers are stereoisomers which are neither mirror images nor identical. If two stereoisomers are not enantiomers, then they are Diastereomers.
(c)
Interpretation:
The blank in the given sentence should be filled by suitable word.
Concept introduction:
Diastereomers are stereoisomers which are neither mirror images nor identical. If two stereoisomers are not enantiomers, then they are Diastereomers.
