A chemist wants to resolve a particular amine, but she has only meso-tartaric acid on hand.She scans the lab inventory and finds several acids, but they are listed only by their common names, which she does not know or remember. Which of the following acids could she in principle use for the resolution of an amine: magic, maleic, malonic, malic, mandelic, meconic, muconic or myristic acids?
