English to French translations [PRO] Science - Chemistry; Chem Sci/Eng / Jugement - Brevet - Royaume Uni | | English term or phrase: molecules are handed | This is an attempt to show a tetrahedral structure. Conventionally the bonds depicted by single lines are in the plane of the paper: the bonds denoted by a solid wedge (a heavy line may also be used) are out of the paper and the bonds denoted by a dotted wedge (or dotted line) arc into the paper. The picture shows two imaginary molecules with an asymmetric carbon atom C. A, B, X and Y denote different atoms or groups positioned at the apexes of the tetrahedron. Because the molecules are handed, they are called chiral, and the asymmetric carbon atom(s) they contain are called chiral centres.
Dois-je dire "molécules sont l'image l'une de l'autre dans un miroir tout en n'étant pas superposables" ou simplement non superposables... ou autrement?
