I can't seem to figure out why they have different pH levels. Our class tested cis-butendioic acid and trans-butendioic acid and one had a pH of 4 while the other had a pH of 1.
I thought that since we made saturated solutions of both, and we were able to dissolve more cis than trans, would that be why cis had a higher pH than the trans?
Other things I've heard is that since the functional groups are closer to each other on the cis, it is more reactive and more acidic? Doesn't seem like a very good reason to me lol.
Any help would be appreciated.
