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). WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another. The existence of these molecules is determined by concept known as chirality. The word “chiral” was derived from the Greek word for hand, because our hands are good example of chirality ...

WebSep 5, 2024 · Chirality means handedness. It is exhibited by chiral molecules. They exist in pairs of stereoisomers. These are non-superimposable mirror images of each other. They do not have a plane of symmetry. They can rotate plane-polarized light and are optically active. Chirality is a property of molecules. WebChiral contamination.
