optically active उदाहरण वाक्य
उदाहरण वाक्य
- This compound is commercially available as a single enantiomer and the single chiral group present in this molecule is able to drive the entire sequence of organic reactions to a single optically active Taxol endproduct.
- However, there are important classes of lossless materials classified as birefringent or optically active in which this is not the case and a wave's polarization will generally be modified or will affect propagation through it.
- I know if a molecule has symmetry ( i . e . it is achiral ) it is not optically active, also, if a molecule does not have a chiral carbon it too is not optically active.
- I know if a molecule has symmetry ( i . e . it is achiral ) it is not optically active, also, if a molecule does not have a chiral carbon it too is not optically active.
- In this patent, the isolation and characterization of the above pictured optically active intermediate bicyclic ketol ( in parentheses ) has also been described, because they worked at ambient temperature in anhydrous dimethylformamide ( DMF ) solvent.
- An optically active Aze was obtained by treatment of ??-diaminobutyric acid dihydrochloride with a mixture of nitrous and hydrochloric acids to yield ?-amino-?-chlorobutyric acid, followed by elimination of hydrogen chloride and cyclization by treatment with barium hydroxide.
- Unlike what happens in an optically active medium such as a sugar solution, reflecting a polarized beam back through the same Faraday medium does not undo the polarization change the beam underwent in its forward pass through the medium.
- For an optically active substance, defined by [ ? ] ? ? = ? / ?l, where ? is the angle through which plane polarized light is rotated by a solution of mass concentration ? and path length l.
- Based on these results, it is proposed that a mixture of racemic amino acids causes spontaneous and effective optical resolution, even if asymmetric synthesis of a single amino acid does not occur without an aid of an optically active molecule.
- As shown above, Hajos and Parrish worked at ambient temperature in dimethylformamide ( DMF ) solvent using a catalytic amount ( 3 % molar equiv . ) of ( S )-( " )-proline enabling them to isolate the optically active intermediate bicyclic ketol.
