introduction to OC

The specific rotation of a pure enantiomer is +12 degrees . It is isolated frm a reaction with 20% racemisation and 80%retention . what would be its observed angle of rotation??

plzz tell also how to solve problems like these??

20% racemised part gives 0° rotation...

80% retention provides rotation of 80% rotation for 100% pure sample i.e. +9.6°

also since enantiomers have same mass, the concentration is not affected...

thus, the angle of rotation reduces to +9.6°
