CHM 102 P block elements Objective Question

Question

Which of the following statements about the distinctive features of P-block elements is correct regarding oxidation states?
Options
A P-block elements exhibit only one stable oxidation state.
B Oxidation states other than the group oxidation state always differ in steps of 1 unit.
C The lower oxidation state becomes more stable as the group is descended due to the inert pair effect.
Correct Answer
D The higher oxidation state always becomes more stable as the group is descended.
Correct Answer

Option C is the correct answer.

Detailed Explanation

According to page 5, 'P block elements exhibit more than one stable oxidation state. Oxidation state other than the group oxidation state generally differ in steps of 2 units due to inert pair effect. The lower oxidation state becomes more stable as group is descended.'

Hint

Consider the effect that arises from the reluctance of s-electrons to participate in bonding.
