Diagram

The image shown is actually a structural diagram of Maleic Acid, not fumaric. This is so because fumaric acid is a trans isomer of butenedioic acid, not a cis isomer (the OH and O groups should be on opposite sides of the final carbons).

The image is correct. Fumaric acid is the trans isomer, which is what is shown in the image. Maleic acid is the cis isomer, which is what is shown in the image on that page. --Ed (Edgar181) 18:14, 10 October 2006 (UTC)[reply]

cis or trans?

In the diagram how is it the trans isomer if the OH groups are both on the bottom, and the O groups are both on the top of the double bond? Shouldn't they be on opposite sides?— Preceding unsigned comment added by 64.21.7.136 (talk • contribs)

The picture is correct, there is rotation around the single C-C-bonds, and the trans describes the conformation of the double bond. But apparently the picture is a bit misleading. Maybe someone has to change the picture. But I hope this helps. --Dirk Beetstra ^{T C} 18:25, 10 November 2006 (UTC)[reply]

Image:Fumaric acid.svg looks perfect to me. I don't see what the confusion is about. —Keenan Pepper 19:52, 10 November 2006 (UTC)[reply]
