Question

Which one of the following show stereoisomerism?

• A. 2-Butene
• B. 3-Butyl but-1-ene
• C. 2-Methyl butene
• D. 3-Methyl butene

Hint:

Stereoisomerism occurs when compounds have the same connectivity but differ in the arrangement of atoms in space.

Answer 1

The Correct Option is A

Step 1: Stereoisomerism.
Stereoisomerism occurs in compounds that have the same molecular formula but differ in the spatial arrangement of atoms. 2-Butene exhibits cis-trans isomerism, hence it shows stereoisomerism.
Step 2: Conclusion.
The correct answer is (A), 2-Butene.
