Planar chirality

Planar chirality refers to a type of spatial arrangement in certain molecules where the chirality arises from the planar structure of the molecule rather than from a chiral center (usually a carbon atom bonded to four different groups). In planar chirality, the different arrangements around a plane can lead to non-superimposable mirror images, typically as a result of the spatial arrangement of groups around a rigid planar structure, such as a cyclic compound or a flat molecular scaffold.
