WitrynaWith 2 chiral centres, you can have up to 2² = 4 isomers: 1. Both C-F bonds as wedges 2. Both C-F bonds as dashed lines 3. One C-F bond as a wedge; the other C-F bond as a dashed line 4. One C-F bond as a dashed line; the other C-F bond as a wedge Structures 1 and 2 are identical, but Structures 3 and 4 are a pair of enantiomers.

If a carbon atom (or other type of atom) has four different substituents, that carbon atom forms a chiral center (also known as a stereocenter). Chiral molecules often have one or more stereocenters.

In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property.
