So I understand that when you deporotonate a carboxylic acid, you get a RCOO-. This causes a delocalisation in the two oxygen atoms. I read somewhere that because of this delocalisation, it makes it less attractive to Hydrogen ions (protons). This makes the carboxylic acid more stable and thus, a stronger acid. My question is why the hydrogen ion is less likely to reattach. If protons are positively charged, won't there be some kind of attraction to the negatively charged anion of carboxylic acid? Thank you.
