31+ Ideas Label Each Stereogenic Center As R Or S. Label the stereogenic center in each compound as r or s. The right hand and left hand nomenclature is used to name the enantiomers of a chiral compound.
For each chiral centre there are two (and only two!) different ways of arranging the 4 different substituents, which gives rise to two different then you can assign r or s in the traditional way. But does it have 4 diastereoisomers? Each stereogenic atom is assigned a descriptor r or s.
Apparently, these stereocenters are also labelled in r/s fashion.
Assign to each a priority a, b, c, or d, using the sequence rules, such that a > b > c. • since enantiomers are two different compounds, they need to be distinguished by name. The stereocenters are labeled as r or s. Assign priorities to each group.
