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… Web3.1.3 Chirality and specific rotation. 3.1.4 Effects of water. 3.1.5 Mixtures in general. 3.1.6 Fully hydrolyzed sucrose. 3.1.7 Partly hydrolyzed sucrose. 3.1.8 Monitoring reaction progress. ...
