Question

How do you know if a Stereoisomer is Optically Active?

Solution

  1. A light-rotating chiral molecule is said to be optically active. If the molecule rotates in the clockwise direction of plane-polarized light, we call the rotation a dextrorotatory rotation. If it rotates counterclockwise, we call it levorotatory rotation.
  2. For2,3-diol, the number of optically active stereoisomers available is2. They are optically active isomers of d,I.
  3. Chiral molecules are normally optically active, and similar and opposite light rotation can be demonstrated by two enantiomers.
  4. Enantiomers are also often called optical isomers. A 50:50 mixture of all enantiomers is referred to as a racemate or racemic mixture, and the light plane does not rotate.
