Question

which of the following will show geometrical isomerism and why?



a)But-2-ene



b)propene



c)But-1-ene

Answer 1

I think But-2-ene show isomerism because in this same molecular formula and can form different structure

Answer 2

Answer:

The answer should be (a)But-2-ene

Explanation:

It shows geometrical isomerism because, Geometric isomers are two or more coordination compounds which contain the same number and types of atoms, and bonds but which have different spatial arrangements of the atoms.

In But-2-ene in one case, the CH3 groups are on opposite sides of the double bond, and in the other case they are on the same side. It means it shows both cis and trans isomerism. That's why it shows geometrical isomerism.
