Chiral molecule with two centers
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. WebRecall that a chiral center in a molecule, such as in (R)-2-butanol, is a tetrahedral atom with four different substituents. Some molecules, such as butane-2,3-diol, have multiple …

WebA chiral centre is an atom that has four different groups bonded to it in such a manner that it has a nonsuperimposable mirror image. The term "chiral centre" has been replaced by the term chirality centre. In the molecule below, the carbon atom is a chirality centre. It has four different groups attached, and the two structures are ...
