Geometrical isomers differ in spatial arrangement of atoms. Which of the following is an example?

  1. CH3—CH=CH—CH3
  2. CH3—CH2—CH=CH2
  3. CH3—CH—CH2—CH3
  4. CH3—CH2—CH2—CH3

Correct answer: CH3—CH=CH—CH3

Solution

Geometrical isomerism arises in compounds with restricted rotation around a double bond and different groups attached to the doubly bonded carbons. CH3—CH=CH—CH3 exhibits this property, forming cis and trans isomers.
