Homework 6C.11

I was having some trouble trying to explain why 2,4,6trichlorophenol is the stronger acid. I know that it is the stronger acid because of the given Ka values, but I'm not sure why exactly this is when looking at the diagram. Any help is appreciated :) A screenshot of the problem is attached for reference.

Hi! I think it may have something to do with polarity or repulsion. Since there are more Cl the H can detach easier and therefore is a stronger acid. Hope this helps

There are more electrons shared across the molecule and that makes H's bond more easily broken. This in turn makes the trichlorophenol stronger.
