Which of the following are arranged in an increasing order of their bond strengths ?

Which of the following statements is true ?

In $\mathrm{XeF}_2, \mathrm{XeF}_4, \mathrm{XeF}_6$ the numebr of lone pairs of $\mathrm{Xe}$ are respectively

Arrange $\mathrm{Ce}^{+3}, \mathrm{La}^{+3}, \mathrm{Pm}^{+3}$ and $\mathrm{Yb}^{+3}$ in increasing order of their ionic radii

Which of the following ions has the maximum magnetic moment ?

When $\mathrm{KMnO}_4$ acts as an oxidising agent and ultimately forms $\left[\mathrm{MnO}_4\right]^{-1}, \mathrm{MnO}_2, \mathrm{Mn}_2 \mathrm{O}_3, \mathrm{Mn}^{+2}$ then the number of electrons transferred in each case respectively is

In case of nitrogen, $\mathrm{NCl}_3$ is possible but not $\mathrm{NCl}_5$ while in case of phosphorous, $\mathrm{PCl}_3$ as well as $\mathrm{PCl}_5$ are possible. It is due to

When $\mathrm{H}_2 \mathrm{~S}$ is passed through $\mathrm{Hg}_2 \mathrm{~S}$ we get
