Q75 / 200 · NEET 2005 · Chemistry

Which one of the following pairs represents stetreoisomerism?

  • A
    Structural isomerism and geometric isomerism
  • Correct answer
    B
    Optical isomerism and geometric isomerism
  • C
    Chain isomerism and rotational isomerism
  • D
    Linkage isomerism and geometric isomerism

Solution

Types of stereoisomerism are optical isomerism and geometrical isomerism. (Ref. to Fig. 27.1) Figure
Related Theory Diastereomers which differ in only one stereocenter (out of two or more) are called epimers. D-glucose and D-galactose can therefore be refered to as epimers as well as diastereomers.

Hence, the correct answer is option: 'B'.
