JEE Advanced Chemistry question

Stability of and halide complexes are in the order

(A)I > Br > Cl > FCorrect
(B)F > Cl > Br > I
(C)Cl > F > I > Br
(D)Br > I > Cl > F

Answer: (A)

Solution

and are "soft" Lewis acids that bond preferentially with "soft," highly polarisable ligands through greater covalent-character overlap. Among the halides, polarisability increases
