WebChiral centers. An atom with four different groups bonded to it in such a way that it has a non-superimposable mirror image is called a chiral center. "The objects which are non-superimposable on their mirror image are said to be chiral and this property is known as chirality''. An example of chirality is a pair of hands. WebExplanation: (2R,4S)-Dibromopentane is superimposable on its mirror image, so it is achiral (i.e., not chiral). Achiral molecules which have chirality centers are called meso compounds. Meso compounds are possible if two (or more) chirality centers in a molecule have the same set of four substituents.

Web100% (1 rating) Transcribed image text: Which of the following is the definition of a meso compound? a. A molecule with chirality centers which is chiral b. A diastereomer with no chirality centers c. A chiral compound with more than one chirality center A molecule with chirality centers having either a plane of symmetry or center of symmetry. WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H. C2 is therefore #2, and C5 is #3. If you assign these priorities to the groups, the sequence 1 → 2 → 3 goes in a counterclockwise direction (S). tesis greatWebDec 17, 2024 · A meso compound contains a plane of symmetry and so is achiral, regardless of whether the molecule has a chiral center. A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each other. By definition, a molecule that's not superimposable on its mirror image is a chiral molecule. tesis geriatria
