How do you calculate optical rotation

How do you calculate optical rotation- The specific rotation of a chemical compound α is defined as the observed angle of optical rotation α when planepolarized light is passed through a sample with a path length of 1 decimeter and a sample concentration of 1 gram per 1 deciliter The specific rotation of a pure material is an intrinsic property of that material at a given wavelength and temperatureTartaric acid) were also capable of optical rotation In the 1800's, it was thought that organic compounds could only be produced through the action of a vital force in living organisms The discovery of optical rotation is in agreement with vitalism because organic materials behaved differently from inorganic materials

 The "optical purity" is a comparison of the optical rotation of a pure sample of unknown stereochemistry versus the optical rotation of a sample of pure enantiomer It is expressed as a percentage If the sample only rotates planepolarized light half as much as expected, the optical purity is 50%Answer It is symetry along 23 bond So it has plane of symetry which makes it optically inactive So, optical rotation = zeroApplications Specific rotation is defined as the angle of rotation in degrees of the plane of polarization of monochromatic light passing through a 100 ml long tube containing an optical active substance in solution at a concentration of 1 g/ml The specific rotation is eg one important parameter to control the purity of optical active substances of incoming products for the production

If optical rotation produced by is 36° then that produced by is (1) – 36° (2) 0° (3) 36° (4) Unpredictable 57 Optical Rotation An equal mixture of two enantiomers is called a racemic mixture or racemate If two enantiomers rotate planepolarized light in opposite directions, a racemate will not rotate light at all The effects of the two enantiomers will cancel out Figure 57 1 Optical rotation canceled out in a racemic mixtureOptical activity is the ability of some substances to rotate the plane of polarization of light passing through them The rotation is detected with a polarizing filter or analyzer Glass and plastic become optically active when stressed;

 Biaxial Positive A mineral is biaxial positive if β is closer to α than to γ;If the optical rotation produced is 130 and the specific rotation is 650 , determine the strength of the solution 31 A cm length of a certain optically active solution causes right handed rotation of 400 , and a 30 cm length of an another solution causes a left handed rotation of 240Optical Activity When a beam of plane polarized light is passed through a solution of a chiral compound such as (S)alanine, the plane of polarization of the light that emerges is rotated relative to the original plane This phenomenon is known as optical activity, and compounds that rotate the plane of polarized light are said to be optically
