Which type of isomerism is exhibited by 2-Butene?
Correct answer: B. Geometric isomerism
- A. Tautomerism
- B. Geometric isomerism
- C. Functional group isomerism
- D. Metamerism
Explanation
2 butene has two different groups on each carbon of the double bond and rotation about it is restricted, so it exists as cis and trans geometric isomers. Tautomerism needs the movement of a proton between two forms, such as keto and enol, and metamerism occurs in ethers, ketones and amines.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
