Question
Which of the following is the strongest nucleophile in an aqueous solution?
Correct Answer
Option D is the correct answer.
Detailed Explanation
In aqueous solution, nucleophilicity follows the order I- > Br- > Cl- > F- (for halides). Iodide is the most polarizable and therefore the strongest nucleophile among halides in water.
Hint
Which halide ion is the most polarizable?
