Question
Account for the following :
Reducing character decreases from SO2 to TeO2.

Solution
As the size of group 16 elements increases down the group, the element–oxygen bond strength decreases from SO2 to TeO2. Therefore, the bond dissociation enthalpy decreases. Hence, due to increase in the tendency to release oxygen, the oxidising tendency increases and, consequently, the reducing character decreases.
