WebAug 29, 2014 · Stereocenters are labeled R or S. The "right hand" and "left hand" nomenclature is used to name the enantiomers of a chiral compound. The stereocenters are labeled as R or S. Consider the first picture: a curved arrow is drawn from the highest priority ( 1) substituent to the lowest priority (4) substituent. WebEnantiomers and diastereomers are the only two stereochemical relationships that you can have between any two molecules. The stereoisomers are any two molecules that fulfill the following two requirements: Both molecules must have the same molecular formula, and. Both molecules must have the same atom connectivity.

WebExplanation: The cis-trans definition is unambiguous only when you have two different groups on one of the alkene carbons and the same two groups on the other carbon, as in but-2-ene. Then the two identical methyl groups are either cis or trans to each other, and the two identical hydrogen atoms are either cis or trans to each other. WebJust as with acyclic compounds, cyclic compounds can have geometric and optical isomers. In general, if any two sp³ carbons in a ring have two different substituent groups (not … how do i freeze a pane in excel
