Question

Do either maleic or fumaric acids have dipolemoment?

Answer 1

I don't KNOW the answer to your question but I would think that maleic acid would have a dipole moment (perhaps not a large one) because it is not symmetrical and fumaric acid would be zero because it is symmetrical. I found a web site that listed maleic as ?D and one listing fumaric as 0 D.
