Q. For (i) I⁻, (ii) Cl⁻, (iii) Br⁻, the increasing order of nucleophilicity would be
A) Cl– < Br– < I–
B) I– < Cl– < Br–
C) Br– < Cl– < I–
D) I– < Br– < Cl–
Explanation
[Solution from source] In protic solvents the larger, more polarisable iodide is least solvated and the best nucleophile, so nucleophilicity increases Cl⁻ < Br⁻ < I⁻. The reverse order applies to basicity, not nucleophilicity. Answer (1).
