Answer :
The percentage of the excess stereoisomer in the mixture c.25%.
Stereoisomerism, or spatial isomerism, is a form of isomerism wherein molecules have the same molecular components and series of bonded atoms, but fluctuate in the three-dimensional orientations of their atoms in space.
The observed rotation of the mixture is levorotary (terrible, counter-clockwise), and the precise rotation of the pure S enantiomer is given as dextrorotary (fantastic, clockwise), which means that the pure R enantiomer should be levorotary, and the mixture has to comprise extra of the R enantiomer than of the S enantiomer.
Enantiomers have the same chemical and bodily homes and are indistinguishable from every other except for the route of rotation of the plane of polarized mild. they're described as optically lively.
