Question

The anion having highest polarizability is
(1) F-
(2) CH-
(3) Br-
(4)I-​

Answer 1

Explanation:

Anions of lower charge density are more polarizable. For anions having the same charge, the larger anion is polarised to a greater extent (F– < Cl– < Br– < I–). For anions of similar size, the more polarizable anion has a greater negative charge (S2– > Cl–).
