Stereoisomerism overviewEasyQuestion 810003

Question

Cis-trans isomers arise due to:
  1. A
    Restricted rotation around C=C double bond
    Correct
  2. B
    Different carbon skeletons
  3. C
    Different functional groups
  4. D
    Optical activity

Correct answer

Restricted rotation around C=C double bond

Explanation

Geometrical (cis-trans) isomerism occurs because C=C bonds cannot rotate freely. The cis isomer has same groups on the same side of the double bond; trans has them on opposite sides.
