(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.

- Which of the following statement is NOT correct? 2 3 4 a. b. C. d. a b C d Constitutional isomers are compounds whose atoms are connected differently. Stereoisomers are compounds whose atoms are connected in the same order but with a different spatial arrangement. Diastereomers are stereoisomers that are mirror images. Molecules that are not identical to their mirror images are a kind of stereoisomers called enantiomers.arrow_forward1. Identify the relationship between the following two structures.a.
