Which of the following compounds will exhibit cis-trans (isomerism) choose which one is correct:
Correct answer: D. 2- butene
- A. Butanal
- B. 2-butyne
- C. 2-butanol
- D. 2- butene
Explanation
Only compounds with a double bond and atleast 2 different substituents on either side can exhibit cis-trans isomerism. Cis- 2-butene has both methyl groups on the same side of the molecule.Trans-2-butene has the methyl groups on opposite sides of the molecule.Their structural formulas are as .

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
