Stereoisomerism

Хиральность
Хиральность
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. ...
Изомерия
Изомерия
Isomers are molecules with the same molecular formula but different structural arrangements. Isomers can be further classified into constitutional isomers ...
Стереоизомеры
Стереоизомеры
On the basis of mirror symmetry, stereoisomers of an organic molecule can be further classified into diastereomers and enantiomers. Diastereomers are ...
Именование энантиомеров
Именование энантиомеров
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral ...
Свойства энантиомеров и оптическая активность
Свойства энантиомеров и оптическая активность
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their ...
Молекулы с несколькими хиральными центрами
Молекулы с несколькими хиральными центрами
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one ...

Стереоизомерия циклических соединений
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular ...
Хиральность азота, фосфора и серы
Хиральность азота, фосфора и серы
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, ...
Прохиральность
Прохиральность
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 ...
Хиральность в природе
Хиральность в природе
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a ...
