Wouldn't the most acidic be the H connected to F? However, my professor says it is answer A, the alpha Hydrogen in carboxylic acid.
Edit: Sorry, I did not phrase my question right. What I meant to say is I thought that the H connected to the same carbon as F would be the most acidic. Also, my professor just sent the answer and did not say why A is the most acidic. I just assumed she meant the alpha H in the carboxylic acid, or is that only for ketone and aldehyde?
