stereochemistry of tartaric acid

Tartaric acid

Tartaric acid is a white crystalline organic acid that occurs naturally in many fruits most notably in grapes but also in bananas tamarinds and citrus Its salt potassium bitartrate commonly known as cream of tartar develops naturally in the process of winemaking It

OPTICAL RESOLUTION – STEREOCHEMISTRY

STEREOCHEMISTRY Optical resolution refers to the separation of two different enantiomers from each other Very rarely this has been done if the crystalline form s of two enantiomers are visibly different from each other For example Louis Pasteur was able to separate the two enantiomers of tartaric acid from each other because the two compounds just happened to crystallize

Stereochemistry

Stereochemistry can trace its roots to the year 1842 when the French chemist Louis Pasteur made an observation that the salts of tartaric acid collected from a wine production vessel have the ability to rotate plane-polarized light whereas the same salts from different sources did not have this ability This phenomenon is explained by optical

Stereochemistry

The fundamental principles of stereochemistry were estab lished by Louis Pasteur in a series of investigations on tartaric acid carried out chiefly during the years 1849-53 Tartaric acid is obtained as a by-product in the manufacture of wine being deposited from the fermented must in the form of potassium hydrogen tartrate The crude salt

Local and Global Chirality at Surfaces: Succinic Acid

A detailed comparison of tartaric acid (HOOC−CHOH−CHOH−COOH) and succinic acid (HOOC−CH2−CH2−COOH) molecules on a Cu(110) surface is presented with a view to elucidate how the two-dimensional chirality exhibited by such robust chemisorbed systems is affected when both OH groups of the former molecule are replaced with H groups a stereochemical

Stereochemistry

Stereochemistry Term originated c 1878 by Viktor Meyer (1848–97) for the study of stereoisomers (see isomer) Louis Pasteur had shown in 1848 that tartaric acid has optical activity and that this depends on molecular asymmetry and Jacobus H van't Hoff and Joseph-Achille Le Bel (1847–1930) had
