WebAug 27, 2024 · A compound incapable of optical rotation is said to be optically inactive. All pure achiral compounds are optically inactive. eg: Chloroethane (1) is achiral and does not rotate the plane of plane-polarized light. Thus, 1 is optically inactive. Table of Contents show How do you know if A compound is optically inactive? WebJan 23, 2024 · Optical Activity Analysis When the optical activity of a meso compound is attempted to be determined with a polarimeter, the indicator will not show (+) or (-). It simply means there is no certain direction of rotation of the polarized light, neither levorotatory (-) and dexorotatory (+). Problems

WebThe specific optical rotation for the pure enantiomer is . Percent optical purity The sample consists of 75 % of the racemic form (=equimolar mixture of both enantiomers, α=0 o ) and an excess of 25 % of the enantiomer in question (62.5 % and 37.5 %). WebOptical purity is another term for enantiomeric excess. This is because chiral chemicals are “optically active,” which means they rotate plane-polarised light.
