WebIn stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms … WebOrganic Chemistry. An important element in organic chemistry is optical isomers (chiral molecules). They are also called chirality, and even though they may appear to have the same structural formula, the presence of a chiral center results in a mixture of completely different compounds. In organic chemistry, optical isomers must be clearly ... WebChirality. Chirality / kaɪˈrælɪtiː / is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ ( kheir ), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. how does water recycling work

WebMar 6, 2012 · Drug isomerism has opened a new era of drug development. Currently, knowledge of isomerism has helped us in introducing safer and more effective drug alternatives of the newer as well as existing drugs. Many existing drugs have gone chiral switch i.e., switching from racemic mixture to one of its isomers. WebAnother common type of isomer is positional isomerism. Positional isomers have the same chemical formula but a different carbon chain numbering of their functional groups. For example, the formula C 4 H 9 OH could be butanol. If we assume it is a straight 4-carbon chain with the alcohol group (-OH), it could be drawn and named in the following ... how does water reach a drainage basinWebMay 1, 1992 · Diastereoisomers and geometric isomers are both chemically distinct and pharmacologically different (unless they are interconverted in vivo) and are generally readily separated without chiral ... how does water retention occur

"In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property.
