WebOptical Activity Chiral molecules, as we learned in the introduction to this chapter, have an interesting optical property. You may know from studying physics that light waves are oscillating electric and magnetic fields. In ordinary light, the oscillation is randomly oriented in an infinite number of planes. Weboptical activity, the ability of a substance to rotate the plane of polarization of a beam of light that is passed through it. (In plane-polarized light, the vibrations of the electric field …

WebThe term optical activity is derived from the interaction of chiral materials with polarized light. In a solution, the (−)-form, or levorotatory form, of an optical isomer rotates the plane of a beam of linearly polarized light counterclockwise. The (+)-form, or dextrorotatory form, of an optical isomer does the opposite. WebAn example of optical isomerism in drugs is the common painkiller Ibuprofen. Ibuprofen consists of two enantiomers, also known as (S+) and (R-) forms. Although both forms have identical boiling points, solubility, and other physical properties, the (R-) form has absolutely no effect on the body. Ibuprofen.
