The conversion of optically pure isomer (enantiomer) into a mixture of equal amounts of both dextro and levo forms is called as: (A) Polymerization, (B) Stereoisomerization, (C) Racemization, (D) Fractionation
Answer is C. Depending on the rotation, molecules are called dextrorotatory (+) (d) or levorotatory (-) (l). Thus D-glucose is dextrorotatory but D-fructose is levorotatory. Equimolecular mixture of optical isomers has no net rotation (racemic mixture) or Racemization Ref: Textbook of Biochemistry for Medical Students, 7E (DM Vasudevan)(2013) Pg no.70 & 71.
