9.19 Consider the reaction of water with F2 and suggest, in terms of oxidation and reduction, which species are oxidized/reduced.
9.15 Saline hydrides are known to react with water violently producing fire. Can CO2, a well-known fire extinguisher, be used in this case? Explain.
9.14 Among NH3, H2O and HF, which would you expect to have highest magnitude of hydrogen bonding and why?
9.13 How does the atomic hydrogen or oxy-hydrogen torch function for cutting and welding purposes? Explain.
9.11 What do you understand by the term “non-stoichiometric hydrides”? Do you expect this type of the hydrides to be formed by alkali metals? Justify your answer
9.1o Do you expect the carbon hydrides of the type (CnH2n + 2) to act as ‘Lewis’ acid or base? Justify your answer.
9.9 What characteristics do you expect from an electron-deficient hydride with respect to its structure and chemical reactions
9.8 What do you understand by (i) electron-deficient, (ii) electron-precise, and (iii) electron-rich compounds of hydrogen? Provide justification with suitable examples.
9.7 Discuss the consequences of high enthalpy of H–H bond in terms of chemical reactivity of dihydrogen?
9.5 Describe the bulk preparation of dihydrogen by an electrolytic method. What is the role of an electrolyte in this process?
9.3 Why does hydrogen occur in a diatomic form rather than in a monoatomic form under normal conditions ?
