Stereoisomerism
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…
Isomers are molecules with the same molecular formula but different structural arrangements. Isomers can be further classified into constitutional…
On the basis of mirror symmetry, stereoisomers of an organic molecule can be further classified into diastereomers and enantiomers. Diastereomers are…
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a…
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their…
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one…
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic…
A racemic mixture, or racemate, is an equimolar mixture of enantiomers of a molecule that can be separated using their unique interaction with chiral…
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the…
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen,…
The concept of prochirality leads to the nomenclature of the individual faces of a molecule and plays a crucial role in the enantioselective…
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a…
