Question

Butene has two isomers—one with methyl groups on the same side of the double bond and the other with methyl groups on the opposite side. What kind of isomers are these?. A) Structural Isomers. B) Geometric Isomers. C) Halotropic Isomers

Answer 1

B) Geometric Isomers

Step-by-step explanation:

In this case, we have a different orientation for the methyl groups on both sides of the double bond. In one of the structures, we have both methyl groups on the same side in the other we have the methyl groups on opposite sides (figure 1).

So, the only thing that changes is the spatial arrangements therefore we will have geometric isomers.

Answer 2

The correct answer among the choices given is option A. The two isomers of butene are structural isomers. This type of isomerism is a form where the molecules have the same molecular formula however the atoms are bonded in different orders.
