WebAug 25, 2011 · Earlier experimental [5,27,28,29,31] and theoretical studies showed that the ester group is oriented anti-periplanar relative to the CF 3 group, and syn-periplanar with respect to the proton of the chiral carbon. The ester, the CF 3 groups as well as the C-H bond of the chiral carbon are coplanar which makes this part of the molecule rigid.

WebThe chiral nanotubes are formed for m ≠ n and chiral angle, 0 ∘ ≤ θ ≥ 30 ∘ [48]. CNTs with n − m = 3 i (where i is an integer) have curvature induced energy band-gap typically of the order of few meV. However, carbon nanotubes for which n − m ≠ 3 i, have larger energy band-gap ∼ 1 eV [49,50]. WebThis important type of stereoisomer occurs because carbon sp 3 tetrahedral centers can allow a molecule to show chirality. Chirality exists when the mirror image reflection of a configuration at an sp 3-hybridized center cannot be exactly superimposed, or placed to match exactly, on the original. Therefore, the mirror images are then two ...
