Estereoisomerismo

Quiralidade
Quiralidade
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 ...
Estereoisômeros
Estereoisômeros
On the basis of mirror symmetry, stereoisomers of an organic molecule can be further classified into diastereomers and enantiomers. Diastereomers are ...
Nomenclatura de Enantiômeros
Nomenclatura de Enantiômeros
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral ...
Propriedades de Enantiômeros e Atividade Óptica
Propriedades de Enantiômeros e Atividade Óptica
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their ...
Moléculas com Múltiplos Centros Quirais
Moléculas com Múltiplos Centros Quirais
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one ...
Projeções Fischer
Projeções Fischer
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A ...
Misturas Racêmicas e a Resolução de Enantiómeros
Misturas Racêmicas e a Resolução de Enantiómeros
A racemic mixture, or racemate, is an equimolar mixture of enantiomers of a molecule that can be separated using their unique interaction with chiral ...
Estereoisomerismo de Compostos Cíclicos
Estereoisomerismo de Compostos Cíclicos
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular ...
Quiralidade em Nitrogênio, Fósforo e Enxofre
Quiralidade em Nitrogênio, Fósforo e Enxofre
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, ...
Proquiralidade
Proquiralidade
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 ...
Quiralidade na Natureza
Quiralidade na Natureza
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a ...
