Question

The number of ions from the following that are expected to behave as oxidising agent is: $\text{Sn}^{4+}, \, \text{Sn}^{2+}, \, \text{Pb}^{2+}, \, \text{Tl}^{3+}, \, \text{Pb}^{4+}, \, \text{Tl}^{+}$

• A. 3
• B. 4
• C. 1
• D. 2

Answer 1

Answer: (D)

2

Answer 2

Due to the inert pair effect, $\text{Tl}^{3+}$ and $\text{Pb}^{4+}$ can behave as oxidising agents.
Thus the correct answer is Option 4.
