Question

The decrease in stability of higher oxidation state in p-block with increasing atomic number is due to:
A. increase in bond energy as going down the group.
B. the reluctance of s-sub shell electrons to participate in the chemical bonding.
C. both are correct.
D. Noble gas configuration achieved by lower oxidation state.

Answer 1

Correct Answer - B
Down the group the inert pair effect is more pronounced on account of enhanced increase in effective nuclear charge.
