The decreasing order of ease of alkaline hydrolysis for the following esters is

Options:

Answer:

Solution:

The rate of hydrolysis depends on a molecule's propensity to accept $O H^{-}$ ions. The rate of hydrolysis is proportional to the $- M$ effect or $- I$ effect of the ester. Note that $- M > - I$ .

The $- N O_{2}$ group is a strong electron-withdrawing group (EWG), $- Cl$ is a weak EWG, and $- OC H_{3}$ is an electron-donating group (EDG).
