Question

The decreasing order of ease of hydrolysis of the following esters is :
(I) `MeCOOPh`
(II)
(III)
(IV) .
A. `(II) gt (I) gt (IV) gt (III)`
B. `(I) gt (II) gt (III) gt (IV)`
C. `(III) gt (IV) gt (I) gt (II)`
D. `(IV) gt (III) gt (II) gt (I)`

Answer 1

Correct Answer - A
More `EWG` favours acyl substitution or hydrolysis of acid derivative.
`II [(-NO_2),(-I)`, and `(-R)], gt (I) [(Ph),(-I)`, and` (+R), ("Standard")] gt (IV) [Me,(+I)` and `H.C.]gt (III) [("Ome"(-I)` and `(-R)`, net more `EDG` than (IV)].
