Why is 2,4,5-trifluorophenol much more acidic than phenol?
A) The fluorines adjacent to the OH group are large and shield the hydroxl group from making the solution basic.
B) The fluorines de-stabilize the benzene ring and thus give the structure more acidic characteristics.
C) The fluorines have high electronegativities and help to stabilize the negative charges, which makes it even easier for the hydrogen to be lost.
D) False! 2,4,5-trifluorophenol is actually not more acidic than phenol.
