Chemistry absolute configuration
WebVideo transcript. the RS system is used to describe the configuration of a chirality center. Down here we have a pair of enantiomers. On the left we have one compound, on the right we have its mirror image. We're going to assign an R orS to each of our enantiomers so let's start with step one. WebNov 9, 2024 · Configuration refers to the arrangement of atoms or groups of atoms in a molecule. There are two types of configurations as absolute configuration and relative configuration. These terms are used specifically for organic compounds having substituents. CONTENTS. 1. Overview and Key Difference 2. What is Absolute …

WebFeb 10, 2016 · Absolute stereochemistry is retained in this case because the highest priority substituent is becoming the lowest priority substituent. If you were to find the absolute stereochemistry of $\ce{2 ->3->4}$ in (R)-bromochlorofluoroiodomethane, which becomes $\ce{1->2->3}$ after attack, you would see that it is S and after attack becomes …
