For the following, (i) I ⁻ (ii) Cl ⁻ (iii) Br ⁻ the increasing order of nucleophilicity would be
Options
- ABr ⁻ Cl ⁻ I ⁻
- BI ⁻ Cl ⁻ Br ⁻
- CCl ⁻ Br ⁻ I ⁻
- DI ⁻ Br ⁻ Cl ⁻
Correct answer
D. I ⁻ Br ⁻ Cl ⁻
Step-by-step solution
Halogens are the most reactive elements. High reactivity is due to their low dissociation energy. Further, among halogen, reactivity decreases as we move down the group. Hence, the correct order of nucleophilicity would be I ⁻ Br ⁻ Cl ⁻
