Fluxional compounds
WebMar 31, 2015 · A fluxional molecule is one that undergoes a dynamic molecular process that interchanges two or more chemically and/or magnetically different groups a … WebJan 24, 2024 · A number of compounds are known to rearrange from one structure to an entirely equivalent structure, sometimes with extraordinary facility. Such compounds are said to be fluxional to distinguish from tautomers (which usually involve rearrangements between nonequivalent structures).

WebJul 31, 2024 · The presence of a phenyl group in a compound can be ascertained with a fair degree of certainty from its infrared spectrum. For example, in Figure 22-1 we see the infrared spectra of methylbenzene, and of 1,2-, 1,3-, and 1,4-dimethylbenzene. That each spectrum is of a benzene derivative is apparent from certain common features. WebMay 1, 1998 · Gridnev and Meller investigated fluxional behaviour of 1-Indenyl(dihydro)borane in 1998 [5].

Cyclohexane and related rings The interconversion of equivalent chair conformers of cyclohexane (and many other cyclic compounds) is called ring flipping. Carbon–hydrogen bonds that are axial in one configuration become equatorial in the other, and vice versa. At room temperature the two chair … See more In chemistry and molecular physics, fluxional (or non-rigid) molecules are molecules that undergo dynamics such that some or all of their atoms interchange between symmetry-equivalent positions.
