Chiral carbon isomers
WebThe lack of a plane of symmetry makes the carbon chiral. The presence of a single chiral carbon atom sufficient to render the molecule chiral, and modern terminology refers to … WebMay 10, 2024 · The second carbon is chiral (carbon attached to four different substituents). The position of Bromine determines the configuration of the molecule. If Bromine is on the left, the molecule is denoted as L and denoted as D if it is on the right. In carbohydrates, the penultimate carbon is observed. If the -OH group is on the left it is L, …

WebSuch molecules are chiral. Molecules that have a plane of symmetry are achiral; they are superimposable on their mirror image. A stereogenic center in an organic molecule is a carbon atom bonded to four different atoms or groups of atoms. It is also called a chiral center.
