Chirality chart
WebBoth the left and right hand are chiral (ky-ral) and show chirality. Chiral is derived from the Greek word cheir, which means “hand”, and chirality means “handedness”. Figure 5.3a Left hand and right hand are non-superimposable mirror images. The definition of chirality is the property of any object (molecule) being non-superimposable ... WebChirality is derived from the Greek word χειρ (kheir) that stands for "hand". An object is said to be chiral if the object and its mirror image are non-superimposable, just like our right and left hand. Now you must be wondering what we mean by ‘non-superimposable’.
