Xenon hexafluoride \( \text{XeF}_6 \) undergoes complete hydrolysis to form XeO\(_3\) and HF.
The structure of \( \text{XeO}_3 \) shows Xe bonded to three oxygen atoms and one lone pair, making a total of 4 regions of electron density.
This corresponds to sp\(^3\) hybridisation.
\( sp^3 \)
Samples of four metals A, B, C, and D were added one by one to the following solutions. The results obtained were tabulated as follows:
Use the table above to answer the following questions about metals A, B, C, and D:
(i) Which is the least reactive metal?
(ii) What would be observed if C is added to a solution of copper sulphate?
(iii) Arrange the metals A, B, C, and D in the order of their decreasing reactivity.
