WebPlane-polarized light is rotated by the helix, and when the pitch of the helix is comparable to the wavelength of visible light, these phases will reflect irridescent light of a single color. The smectics phases can exhibit ferroelectricity and have … Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl.

WebOnly chiral biphenyls are optically active. All chiral compounds are optically active. Optical activity can be determined experimentally using polarimeter tube which measures the specific rotation of light passing through the device. Alternatively the structure of the molecule can be used to determine whether the molecule is chiral.
