WebNov 3, 2015 · Chiral nanotubes exhibit ferromagnetic coupling at long distances while non-chiral systems usually favor antiferromagnetic coupling. The inclusion of C60 molecules inside the nanotube, resulting in peapod structures, in some cases causes dramatic changes in the coupling interactions and spin density. http://butane.chem.uiuc.edu/cyerkes/chem104A_S07/Lecture_Notes_104/lect23c.html

IN the case of glucose, carbons 2, 3, 4, and 5 are chiral centers. Therefore, there are 2 4 = 2 x 2 x 2 x 2 = 16 stereoisomers of the molecule.
WebThere are 2 chiral carbons, so, 2 2, or 4 possible stereoisomers. This is a D isomer, since the OH on the chiral carbon furthest from the C=O is on the right. The second physical property we will consider is their ability to rotate plane polarized light, arising from the presence of chiral carbons in these molecules.
