I was trying to compare the reactivity between acetaldehyde and benzaldehyde. After some googling, I found out that benzaldehyde is less reactive than acetaldehyde because the benzene ring can stabilize the partially positive Carbon through resonance. However, if I apply the same logic to benzoic acid vs acetic acid, I find that benzoic acid should be less acidic than acetic acid, but that's not true. What am I missing?
