`CH_(3)Br +Nu^(Theta) rarr CH_(3)-Nu +Br^(Theta)` The decreasing order of the rate of the above reaction with nucleophiles `Nu^(Theta) A` to `D` is- `[Nbar(u) =(A) phO^(-), (B) AcO^(-), (C)H bar(O),(D) CH_(3)bar(O)]`A. `(D) gt (C) gt (A) gt (B)`B. `(D) gt (C) gt (B) gt (A)`C. `(C) gt (D) gt (A) gt (B)`D. `(B) gt (D) gt (C) gt (A)` |

Answer» Correct Answer - `c` Acidic character: `underset(pK_(a) "value:")() underset(4.75)(ACOH) gt underset(9.9)(PhOH) gt underset(15.5)(MeOH) gt underset(15.74)(H_(2)O)` Basic and nucelphilic characters are same because of same nucleophilic centre. Nucleophliic order: `{:(AcO^(Theta),lt,PhO^(Theta),lt,MeO^(Theta),lt,overset(Theta)(O)H),((B),lt,(A),lt,(D),lt,(C)):}` |
