How many chiral centers can an achiral molecule have?

WebJul 3, 2024 · Chiral Center Definition. A chiral center is defined as an atom in a molecule that is bonded to four different chemical species, allowing for optical isomerism. It is a stereocenter that holds a set of atoms (ligands) in space such that the structure may not be superimposed on its mirror immage. Web3. Chiral molecules are asymmetric at one or more centres. Achiral molecules are symmetric at all the centres. 4. Chiral molecules rotate plane polarised light in a clockwise or anticlockwise direction. Achiral molecules don’t rotate plane polarised light in any direction. 5. The mirror image of a chiral molecule is a different molecule. dura glove archery
