The correct order of increasing rate of hydrolysis of the following compund is
Answer»
`I LT II lt III` `III lt II lt I` `I lt III lt II` `III lt I lt II`
Solution :The rate determining step in the hydrolysis of an ester is bimolecular, the larger the R, greater will be the steric RETARDATION since HYBRIDISATION of the carbonyl carbon changes from `sp^(2)` to `sp^(3)` (due to increased bonding). The ORDER of increasing rate of hydrolysis is `III lt II lt I`
