WebCyclic olefins afford optically active polymers by asymmetric synthesis polymerization. The first example was the polymerization of benzofuran (265) with AlEtCl 2 or AlCl 3 in the presence of optically active cocatalysts such as β-phenylalanine and 10-CSA; the polymer is considered to possess the chiral erythro- or threodiisotactic structure (266a or 266b). … WebFeb 20, 2007 · 537. 1. Tsunami said: Molecules are optically active when they react differently to left or right circularly polarized light. This is because they have a screw-oriented structure which is itself either left-handed or right-handed, making propagation preferential for one polarisation, rather than for the other. greater victoria british columbia

Manuscript Submission Information WebDec 15, 2024 · The property of a compound being able to rotate the plane of polarization of plane-polarized light is called the optical activity, and the compound with such activity is labelled as optical active. The stereoisomer that is optical active is also called as optical isomer. Chiral compound is optical active. Achiral compound is optical inactive.

Optical activity occurs due to molecules dissolved in a fluid or due to the fluid itself only if the molecules are one of two (or more) stereoisomers; this is known as an enantiomer. The structure of such a molecule is such that it is not identical to its mirror image (which would be that of a different stereoisomer, or the "opposite enantiomer"). In mathematics, this property is also known as chirality. For instance, a metal rod is not chiral, since its appearance in a mirror is not distinct f…
