The toolkit also includes a database of about 60 molecules, as well as comprehensive didactical and technical help files. WebAug 8, 2024 · A chiral compound can contain no improper axis of rotation ( S n ), which includes planes of symmetry and inversion center. Chiral molecules are always dissymmetric (lacking S n) but not always asymmetric (lacking all symmetry elements except the trivial identity). Asymmetric molecules are always chiral. That means that a …
