Which of the following are hydrolysed faster than ethyl acetate by aqueous NaOH at the same temperature and concentration?

Phenoxide and 4-nitrophenoxide are better leaving groups than ethoxide. In ethyl trichloroacetate the three Cl atoms make the carbonyl carbon much more electrophilic. Acetamide is hydrolysed much more slowly because $\mathrm{NH}{}_2{}^{-}$ is a very poor leaving group.
