11. What do you understand by the term \u201cnon-stoichiometric hydrides\u201d? Do you expect this type of the hydrides to be formed by alkali metals? Justify your answer.<\/p>\n

12. How do you expect the metallic hydrides to be useful for hydrogen storage? Explain.<\/p>\n

13. How does the atomic hydrogen or oxy-hydrogen torch function for cutting and welding purposes? Explain.<\/p>\n

14. Among and HF, which would you expect to have highest magnitude of hydrogen bonding and why?<\/p>\n

15. Saline hydrides are known to react with water violently producing fire. Can , a well known fire extinguisher, be used in this case? Explain.<\/p>\n

16. Arrange the following<\/p>\n

(i) in order of increasing electrical conductance.<\/p>\n

(ii) LiH, NaH and CsH in order of increasing ionic character.<\/p>\n

(iii) H-H, D-D and F-F in order of increasing bond dissociation enthalpy.<\/p>\n
