The correct order of reactivity in `S_(N^(1))` reaction for the following compounds is (i). `CH_(3)-underset(Cl)underset(|)(C)H-CH_(2)-CH_(3)` (ii). `Ph-underset(Cl)underset(|)(C)H-CH_(2)-CH_(3)` (iii). `CH_(3)-underset(OC H_(3))underset(|)overset(Cl)overset(|)(C)-CH_(3)` (iv). `CH_(3)-CH_(2)-CH_(2)-Cl`A. `(i)gt(ii)gt(iii)gt(iv)`B. `(ii)gt(i)gt(iii)gt(iv)`C. `(iii)gt(ii)gt(i)gt(iv)`D. `(iv)gt(iii)gt(ii)gt(i)` |
Answer» Correct Answer - C This order of reactivity in `S_(N^(1))` reactions is directly proportional to the relative stabilities of carbocations in the slow step. `therefore` the correct order of reactivity is: IIIgtIIgtIgtIV |
