Geometric isomerism is present in:
Correct answer: D. 2-Butene
- A. Methane
- B. Ethane
- C. Propane
- D. 2-Butene
Explanation
Geometric isomerism, also known as cis-trans isomerism, occurs when there is restricted rotation around a double bond, leading to different spatial arrangements of substituent groups. In 2-Butene, the presence of a double bond restricts rotation, allowing for cis and trans isomers to exist.

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.
