(I) `-OAc`, (II) `-OMe`, (III) `-OSO_(2)Me`, (IV) `OSO_(2)CF_(3)` the order of leaving group ability is-

In the following groups: -O Ac(I),- OMe( II) -O SO_2 Me( III)-O SO_2 CF_3 ( IV) the order of leaving group ability is : IgtIIgtIIIgtIV IVgtIIIgtI.II IIIgtIIgtIgtIV IIgtIIIgtIVgtI

The correct leaving group ability order is :

In the following group : -OAc(I),-OMe(II),-OSO_(2)(III),-OSO_(2)CF_(3)(IV) The order of leaving group ability is :

The order of leaving group ability is .^(-)underset((I))(OAc).^(-) underset((II))(OMe).^(-)underset((III))(SO_3Me).^(-)underset((IV))(SO_3CF_3) The order of leaving group ability is
