QJEEM24Chdf91: JEE Main 2024 Chemistry - Class 11 JEEM24Chdf91 Solution: The number of ions from the following that are expected to…

Due to inert pair effect $\mathrm{Pb}^{2+}$ is more stable than $\mathrm{Pb}^{4+}$ and $\mathrm{Tl}^{+}$ is more stable than $\mathrm{Tl}^{3+}$ . Therefore, $\mathrm{Pb}^{4+}$ and $\mathrm{T}^{3+}$ will function as oxidising agents and easily get reduced to $\mathrm{Pb}^{2+}$ and $\mathrm{TI}^{+}$ respectively.
