Aromatic acids are widely used in many fields such as medicine, food additives, tobacco industry and cosmetics. Therefore, it is necessary to understand and learn the common aromatic acids.
The APP offers a novel, fun way to learn: question-and-answer learning. Through the randomly generated aromatic acid molecular structure, users need to judge and correctly find the corresponding molecular formula /CAS number through learning, that is, the answer is correct. In this way, users can effectively understand and learn aromatic acids, as well as learn their molecular structure system.
