Question

On moving down Group 14, how does the stability of +2 and +4 oxidation states in chlorides change?
Options
A Stability of +4 oxidation state increases, while +2 oxidation state decreases.
B Stability of +4 oxidation state decreases, while +2 oxidation state increases.
Correct Answer
C Both +2 and +4 oxidation states become equally stable.
D Both +2 and +4 oxidation states become less stable.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 14 states: '✓On moving down the group, the stability of +4 oxidation state decreases' and 'the stability of +2 oxidation state increases'. This is typically attributed to the inert pair effect.

Hint

Remember the inert pair effect which becomes more prominent for heavier elements in p-block.
