Optical activity ochem
WebOptical Activity. The stereochemistry of molecules has its roots in the work of the nineteenth‐century French physicist Jean Biot. Biot was studying the nature of plane‐polarized light (Figure 1 ) when he discovered that solutions of some organic compounds caused polarized light to rotate. Compounds with this property are called … WebYou can only find optical activity from experimentation. However, you will notice that if you know the optical activity for one structure, the enantiomer of that compound will have the …

WebOptical Activity - Chirality A carbon atom bddbonded to four diff tdifferent groups could ldlead toopti ltical acti ittivityand is called a stereogenic center. CH 3 CH 2CH 3 HO H In general organic compounds, which lack a plane of symmetry are optical active and are called chiral compounds. OH OH OH OH Achiral Chiral WebA 50:50 mixture of enantiomers has no observable optical activity. Such mixtures are called racemates or racemic modifications, and are designated (±). When chiral compounds are created from achiral compounds, the products are racemic unless a single enantiomer of a chiral co-reactant or catalyst is involved in the reaction.

It will have zero optically activity, so all of the observed rotation comes from the 86 % natural cholesterol. The natural cholesterol then accounts for 86 % + 7 % = 93 % of the mixture.
