網頁There are two general methods for determining the R- or S-configuration: The hand method and the clock method. The hand method points the thumb in the direction of the atom of … 網頁And that is the swap method. The basis of this is that swapping any two groups on a chiral center inverts (changes) its absolute configuration (R to S, S to R): Notice that these are different molecules. We are not talking about rotating about an axis or a single bond, in which case the absolute configuration (s) must stay the same.

網頁Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other. For example, the aldopentoses each contain three chiral centres. Thus, D-ribose is a diastereomer of D-arabinose, D-xylose, and D-lyxose. Epimers are diastereomers that contain more than one chiral center but differ from each other in the … 網頁Lesson 5: Stereochemistry Stereochemistry questions Chiral drugs Structural (constitutional) isomers Chiral vs achiral Stereoisomers, enantiomers, and chirality …
