Rdkit chiral center
Webchiral (stereogenic) centre plane of symmetry Symmetry and Chirality Molecules that are nonsuperimposable mirror images of each other are said to be chiral (pronounced “ky-ral,” from the Greek cheir, meaning “hand”). Examples of some familiar chiral objects are your hands. Your left and right hands are nonsuperimposable mirror images. http://www.dalkescientific.com/writings/diary/archive/2016/08/17/fragment_on_bonds.html
