stereoisomerism meaning in Hindi

Examples

1. Because they have at least one asymmetric carbon center, aldoses with three or more carbon atoms exhibit stereoisomerism.
2. Stereoisomerism about double bonds arises because rotation about the double bond is restricted, keeping the substituents fixed relative to each other.
3. As with other 3-substituted fentanyl derivatives such as ohmefentanyl, the stereoisomerism of lofentanil is very important, with some stereoisomers being much more potent than others.

6. Likewise, the idea of stereoisomerism-that atoms have rigid three-dimensional structure and can thus form isomers that differ only in their three-dimensional arrangement-was another crucial step in understanding the concept of distinct chemical substances.
