Stereochemistry - Chirality, Enantiomers & Diastereomers with Videos

網頁Stereoisomers As defined in an earlier introductory section, isomers are different compounds that have the same molecular formula. When the group of atoms that make up the molecules of different isomers are bonded together in fundamentally different ways, we refer to such compounds as constitutional isomers . 網頁2024年1月28日 · Stereochemistry tends to study the relative arrangement of atoms of two molecules in 3-dimensional space. Stereochemistry can be essentially divided into two types. One studies the geometry of compounds that exhibit chirality, and the other on the effects caused by differences in the 3D arrangement of atoms. It is also known as 3D …
