In stereochemistry, topicity is the stereochemical relationship between substituents and the structure to which they are attached. Depending on the relationship, such groups can be …

2012年4月17日 · When you have two hydrogens attached to a single carbon, they can have three different types of relationships. We call them “homotopic”, “enantiotopic”, and “diastereotopic”. …

What is the definition of topicity? -ity is a suffix "expressing state or condition" (Oxford English Dictionary) and is more or less equivalent to the suffix -ness. Thus chirality and handedness …

Topicity describes relationships between localised areas in the same molecule. Homotopic groups are those that can be interconverted by a proper rotation and are chemically identical If either …

In the present chapter, we redefine topicity terms in the light of chirality fittingness of orbits and then discuss stereogenicity.

2023年1月2日 · In such cases, the topicity (Greek topos meaning “place” or “physical surrounding”) of the two homomorphic ligands (here H’s at C2), in other words, their special …

The topicity in stereochemistry may simply be defined as the stereochemical relationship between substituents and the structure with which they are bonded. Based on such relationships, …

Definition of topicity. These discussions indicate that each position is charac­ terized as a member of a homo-, enantio-, or hemi-spheric orbit. For some pur­ poses, we further examine the …

In chemistry, topicity is the stereochemical relationship of substituents relative to the structure to which they are attached. Depending on the relationship, such groups can be homotopic, …
