racemisation मीनिंग इन हिंदी

उदाहरण वाक्य

1. BINOL has axial chirality and the two enantiomers can be readily separated and are stable toward racemisation.
2. Racemisation of chiral sugars seems pretty rapid-- so why does the optical purity of your lactic acid matter?
3. Bada, & al ., ( 1974 ) published the direct date of 110 ka for this specimen measured by aspartic acid racemisation.
4. During the 1970s and 1980s he developed an important technique of marine sediment dating through the measurement of the racemisation rates of amino acids.
5. Given a set of reaction conditions the reaction is found to be reversible the presence of acid causes a racemisation process simply by mixing chiral aza-BH adduct, phosphine and acid.
6. The difference between S N 1 and S N i is actually that the ion pair is not completely dissociated, and therefore no real carbocation is formed, which else would lead to a racemisation.
7. This reaction takes place with racemisation of the propionic acid ester group of ring C . Oxidation ( iodine / acetic acid ) formed lactone "'62 "'and restored the correct stereochemistry at the ring B propionic acid ester tail.
