I just came across this question in my revision.
I selected (A) but the correct answer is (D).
Could someone explain where I am going wrong?
- I is least stable --> most reactive --> most basic
- Cl is more electronegative than F so III will have a stronger inductive stabilization effect --> III is more stable than II --> III is less reactive than II --> III is less basic than II
- Hence, rank order: I, II, III
