WebSTEREOCHEMISTRY II PROSTEREOISOMERISM Topicity of Ligands and Faces SEM-2, CC-3 PART-2, PPT-6 Dr. Kalyan Kumar Mandal Associate Professor St. Paul’s C. M. Coll… Homotopic groups in a chemical compound are equivalent groups. Two groups A and B are homotopic if the molecule remains achiral when the groups are interchanged with some other atom (such as bromine) while the remaining parts of the molecule stay fixed. Homotopic atoms are always identical, in any environment. Homotopic NMR-active nuclei have the same chemical shift in an NMR spectrum. For example, the four hydrogen atoms of methane (CH4) are homotopic wit…

Web1 sep. 2024 · It is note that most of the nitrogen-containing tripodal ligands only possess one type of nitrogen-donor group and possess a C3 symmetry (namely homotopic ligand). Obviously, such extension strategy does not alter their C3 symmetry. WebLigands that are equivalent by the criteria to be described in the sequel are called homotopic from Greek homos = same and topos = place 6>, those that are not are called heterotopic .
