For (i) I , (ii) Cl^ - , (iii) B r , the increasing order of...

For (i) \overline{\mathrm{I}}, (ii) Cl−\mathrm{Cl}^{-}, (iii) Br‾\mathrm{B} \overline{\mathrm{r}}, the increasing order of nucleophilicity would be

Options

  1. ACl−<Br<1−\mathrm{Cl}^{-} < \mathrm{Br} < 1^{-}
  2. Bl−<Cl−<Br\mathrm{l}^{-} < \mathrm{Cl}^{-} < \mathrm{Br}
  3. CBr<Cl−<1−\mathrm{Br} < \mathrm{Cl}^{-} < 1^{-}
  4. Dl−<Br−<Cl−\mathrm{l}^{-} < \mathrm{Br}^{-} < \mathrm{Cl}^{-}

Correct answer

A. Cl−<Br<1−\mathrm{Cl}^{-} < \mathrm{Br} < 1^{-}

Step-by-step solution

Nucleophilicity increases down the group in a periodic table. I\mathrm{I}^{-}>Br\mathrm{Br}>Cl−\mathrm{Cl}^{-}>\mathrm{F}^{-}
