Explain study diffusion in liquids and methylbenzene

Reference no: EM13535588

Two solutes were used to study diffusion in liquids, methylbenzene, which is a small molecule that can be approximated as a sphere, and a liquid crystal that is long and rod like. The two solutes were found to move and rotate in all directions to the same extent in benzene. In a liquid crystal solvent the methylbenzene again moved and rotated to the same extent in all directions, but the liquid crystal solute moved much more rapidly along the long axis of the molecule than it did in a "sideways" mode, perpendicular to the long axis. It also was found to rotate more rapidly around the long axis than perpendicular to it. Explain this behavior.
