Elements of symmetry in stereochemistry

WebThe chapter of “Stereochemistry” from the book entitled “A Textbook of Organic Chemistry – Volume 1” covers the following topics: Chirality; Elements of symmetry; Molecules with more than one chiral centre: diastereomerism; Determination of relative and absolute configuration (octant rule excluded) with special reference to lactic ... WebThus, diastereomers are stereoisomers that are not enantiomers. If a molecule happens to be symmetric so that two of the four possible stereoisomers are identical (the S,R is identical to the R,S; the S,S and R,R will always be enantiomers), this form …
