Question

22] Increasing order of polarisability : * 4 points S2–, O2–, Se2–, Te2– O2–, S2–, Te2–, Se2– O2–, S2–, Se2–, Te2– None

Answer 1

Answer:

O2(_) < S2(_) < Se2(_) < Te2(_).( 16th group elements).

Explanation:

Remember chemical bonding concepts.

we know for anion,

polarizability directly proportional to size of anion and also directly proportional to covalent nature.
