Examples of chirality centers
WebJun 14, 2014 · Chirality is an important geometric property relating to a molecule's symmetry. A chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot). An achiral molecule is superimposable with its mirror image and do not have "handedness" (think of … WebThe asymmetric atom is called a chirality center, a type of stereocenter. A ... For example, hydrogen peroxide is chiral and has C 2 (two-fold rotational) symmetry. A common chiral case is the point group C 1, meaning no symmetries, which …
