WebChirality. The term "chiral" (from the Greek for "hand") is applied to molecular systems whose asymmetry results in handedness; that is, the existence of a pair of nonsuperimposable mirror-image shapes (as illustrated by the relationship between one's right and left hands). Lord Kelvin coined the term "chirality" in 1884, (Eliel, p.

In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property. WebDepending on the chirality, CNTs can be categorized as an armchair, zigzag, and chiral, as illustrated in Fig. 1.5 [ 60 ]. In the armchair, an arrangement of bonds in one of the chairs is perpendicular to the tube axis; in zigzag, there is an arrangement of bonds in which the tube has a V shape perpendicular to the tube axis.
