WebA stereogenic element is a center, axis or plane that is a focus of stereoisomerism, such that an interchange of two groups attached to this feature leads to a stereoisomer. Stereogenic elements may be chiral or achiral. An asymmetric carbon is often a chiral stereogenic center, since interchanging any two substituent groups converts one ... WebThe term "chiral" in general is used to describe the object that is non-superposable on its mirror image. In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers. Pairs of enantiomers are often designated as "right-", "left-handed" or, if they have no bias, "achiral ...

"WebA molecule's chirality can be determined by several overlapping conditions. Here are two examples of molecules with differing chirality, achiral and chiral. A chiral molecule is distinguished by the presence of two atoms of the same element. If one creates a bisecting plane through the other two atoms, the images on either side are the same.
