Stereoisomeria

Chiralità
Chiralità
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. ...
Isomeria
Isomeria
Isomers are molecules with the same molecular formula but different structural arrangements. Isomers can be further classified into constitutional isomers ...
Stereoisomeri
Stereoisomeri
On the basis of mirror symmetry, stereoisomers of an organic molecule can be further classified into diastereomers and enantiomers. Diastereomers are ...
Nomenclatura degli enantiomeri
Nomenclatura degli enantiomeri
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral ...
Proprietà degli enantiomeri e attività ottica
Proprietà degli enantiomeri e attività ottica
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their ...
Molecole con più centri di chiralità
Molecole con più centri di chiralità
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one ...
Proiezioni di Fischer
Proiezioni di Fischer
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A ...
Miscele racemiche e risoluzione degli enantiomeri
Miscele racemiche e risoluzione degli enantiomeri
A racemic mixture, or racemate, is an equimolar mixture of enantiomers of a molecule that can be separated using their unique interaction with chiral ...
Stereoisomeria dei composti ciclici
Stereoisomeria dei composti ciclici
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular ...
Centri di chiralità: azoto, fosforo e zolfo
Centri di chiralità: azoto, fosforo e zolfo
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, ...
Prochiralità
Prochiralità
The concept of prochirality leads to the nomenclature of the individual faces of a molecule and plays a crucial role in the enantioselective reaction. It ...
La chiralità in natura
La chiralità in natura
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a ...
