Question

Which of the following does NOT exhibit geometrical isomerism? 

पर्याय

• But-2-ene

• Pent-2-ene

• But-1-ene

• Hex-2-ene

Answer 1

But-1-ene

Explanation:

However, because one of the C atoms involved in the double bond formation has two identical (H) atoms attached to it, But-1-ene does not exhibit geometrical isomerism. In contrast, a compound must have different atoms or groups attached to a C atom involved in the double bond formation in order for a compound to exhibit geometrical isomerism.
