Because of the tetrahedral geometry of saturated carbon and the associated three-dimensional properties, molecules can have chirality as one stereochemical feature. Any object is chiral if it is different (nonsuperimposable) than its mirror image. Likewise a molecule is chiral if it is nonsuperimposable on its mir-ror image. option worksheet

Chirality - Stereochemical and Conformational Isomerism

WebChirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item. A chiral item or system is distinct from its mirror image; that is, it cannot be overlaid onto it. Golf clubs, scissors, shoes, and a corkscrew are examples of chiral ... 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.
