Hello! I came across this question in a GAMSAT (med school admission) test paper and was very confused about how to solve it. The test is, in theory, supposed to be more about problem-solving rather than background knowledge, so usually, the answers can be found through reasoning based on the text provided. For these questions, however, I didn't find that to be true. I have done uni chemistry, but I don't recall learning how to predict anionic or cationic products or things that can help identify them. If anyone could help, it would be greatly appreciated!

Do you remember how ammonia behaves in the presence of acids? Amines can be think of as ammonia derivatives.

What do you know about carboxylic acids?
