Taking stability as the factor, which one of the following represents correct relationship?
- A
- B
- C
- D
Solution & Step-by-step Explanation
In Group 13, the stability of the oxidation state increases down the group while the state decreases due to the inert pair effect.For Thallium (), the state is more stable than . Thus, and .For Aluminum () and Indium (), the state is still more stable.Option D correctly reflects that the halide is more stable than the halide for Thallium.
