In which of the following properties, the two enantiomers of lactic acid differ from each other?

Options

  1. ASign of specific rotation
  2. BDensity
  3. CMelting point
  4. DRefractive Index

Correct answer

A. Sign of specific rotation

Step-by-step solution

The compound which is non-superimposable on its mirror image, is called optically active or chiral and its two non-superimposable mirror images are called enantiomers which have all physical and chemical properties same and also rotate the plane polarised light upto same extent but in opposite direction.
