(a) Interpretation: The reason corresponding to the fact that after the reaction of ( R ) − 2 − methylcyclohexanone with NaOH in the presence of H 2 O , the optically active solution gradually loses optical activity is to be stated. Concept introduction: The stereoisomers that possess the mirror images of each other which are not superimposable or not identical to each other are termed as enantiomers. The process of producing the equal mixture of possible enantiomers if any compound undergoes a transformation then this process is termed as racemization. The resultant mixture is known as racemic mixture. The phenomenon by which a chiral molecule is observed to rotate the polarized light in either a clockwise direction or anticlockwise direction is called optical activity of that molecule.
