WebJan 28, 2024 · Introduction. A meso compound is an achiral compound that has chiral centers. A meso compound contains an internal plane of symmetry which makes it superimposable on its mirror image and is optically inactive although it contains two or more stereocenters.Remember, an internal plane of symmetry was shown to make a molecule … WebThe setting is a system containing achiral reactants which form a chiral compound. In 1983, Kondepudiand Nelson proposed a model for the breaking of chiral symmetry. The present article reduces the conditions for bifurcation to a single condition which is shown to be both necessary and sufficient. A number of other papers on this topic also ...
