Q57.The decreasing order of ease of alkaline hydrolysis for the following esters is (1) III > II > IV > I (2) III > II > I > IV (3) IV > II > III > I (4) II > III > I > IV
What This Question Tests
This question evaluates the understanding of how electron-withdrawing or electron-donating groups influence the electrophilicity of the carbonyl carbon and thus the rate of alkaline hydrolysis of esters.
