Which of the following alkenes does \(\underline{NOT}\) exhibit cis-trans isomerism?
- A But-1-ene
- B But-2-ene
- C 3,4-Dimethylhex-3-ene
- D Pent-2-ene
Answer & Solution
Correct Answer
(A) But-1-ene
Step-by-step Solution
Detailed explanation
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 \(\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}=\mathrm{CH}_2\) will not exhibit cis-trans isomerism.
