1. The problem statement, all variables and given/known data So this was a little acid-base reaction that ended up showing up on my quiz. I'm just not sure how to pick out the hydrogen in the group that is the most acidic. I wrote it as being the hydrogen that was attached to the carbon with the double bond. Could anyone explain why that is wrong? And give general guide lines to follow? 2. Relevant equations My reasoning for the hydrogen attached to the carbon with the double bond was because it was sp2 hybridized which generally makes protons more acidic? I'm not sure, my logic is probably flawed, so if someone could correct it that would be much appreciated!
