WebThese two stereoisomers. They're a special type of stereoisomer that we call enantiomers. We'll talk much more about number of stereoisomers in a later video. The next video, we're going to go into more detail about chiral centers and chirality centers, and how to identify the number of chiral centers in a molecule. Up next: video. WebApr 1, 2002 · Stereoisomers are isomers whose atoms, or groups of atoms, differ with regard to spatial arrangement of the ligands, and they can be either geometrical or optical isomers. Geometrical isomers are stereoisomers without optically active centres and result from restricted rotation as a result of the presence of, for example, a carbon– carbon ...

Chirality 25 , 365–368 (2013). WebThe definition of chirality is the property of any object (molecule) being non-superimposable on its mirror image. The left and right hand are mirror images of each other, and they are not superimposable, so both the left hand and right hand are chiral. You can also find many other objects in daily life that show chirality as well.
