Stereochemistry - Wikipedia

WebStereochemistry – Viktor Meyer (1848–97) used the term in 1878 to describe the study of stereoisomers. In 1848, Louis Pasteur demonstrated that tartaric acid has optical activity, which is dependent on molecular symmetry, and in 1874, Jacobus H. van’t Hoff and Joseph-Achille Le Bel (1847–1930) independently demonstrated that a molecule with a carbon … Web5.6 Symmetry and Chirality / Summary • Overall: o The presence or absence of rotational symmetry is irrelevant to chirality. o A compound that has a plane of symmetry is achiral. o A compound without a plane of symmetry will usually be chiral, but there are exceptions (such as a compound with an inversion center).
