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. ...
异构
异构
Isomers are molecules with the same molecular formula but different structural arrangements. Isomers can be further classified into constitutional isomers ...
立体异构体
立体异构体
On the basis of mirror symmetry, stereoisomers of an organic molecule can be further classified into diastereomers and enantiomers. Diastereomers are ...
命名对映异构体
命名对映异构体
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral ...
对映异构体的性质和光学活性
对映异构体的性质和光学活性
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their ...
具有多个手性中心的分子
具有多个手性中心的分子
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one ...
Fischer 投影
Fischer 投影
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A ...
外消旋混合物和对映异构体的分离度
外消旋混合物和对映异构体的分离度
A racemic mixture, or racemate, is an equimolar mixture of enantiomers of a molecule that can be separated using their unique interaction with chiral ...
环状化合物的立体异构
环状化合物的立体异构
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular ...
氮、磷和硫的手性
氮、磷和硫的手性
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, ...
手性
手性
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 ...
自然界中的手性
自然界中的手性
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a ...
