Which of the following alkenes does NOT exhibit cis-trans isomerism?

Options

  1. ABut-1-ene
  2. BBut-2-ene
  3. C3,4-Dimethylhex-3-ene
  4. DPent-2-ene

Correct answer

A. But-1-ene

Step-by-step solution

For any compound to exhibit cis-trans isomerism, it must contain identical atoms or groups of atoms on either side of double bond. Hence, but-1-ene CH ₃- CH ₂- CH = CH ₂ will not exhibit cis-trans isomerism.
