The phenolate ion has the longest λ_max (extinction coefficient) in the UV spectrum compared to the other compounds listed. This is due to the presence of the negative charge on the oxygen atom, which delocalizes the electrons across the aromatic ring, leading to a higher probability of absorption of electromagnetic radiation.
