Tartaric Acid: Structure Where It Is Found Applications

He tartaric acid is an organic compound whose molecular formula is COOH (CHOH) 2 COOH It has two carboxyl groups that is it can release two protons (H + ) In other words it is a diprotic acid Likewise it can be classified as an alderic acid (acidic sugar) and a succinic acid derivative

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

Pasteur — The harbinger of stereochemistry

He separated the oppositely shaped crystals of tartaric acid by handpicking found their optical rotation to be in opposite directions and concluded that this optical property was attributable to the existence of two oppositely shaped tartaric acid molecules Thus the new subject of stereochemistry was heralded
