Explain about the uses of hydrogen compounds.

Explanation

( i) The hydrogen compounds such as sodium borohydride `(NaBH_(4))` and lithium aluminium hydride (LiAIH) are commonly used as reducing agents in organic chemistry.
(ii)Hydrides such as sodium hydride (NaH) and potassium hydride (KH) are used as strong bases in organic synthesis.
(iii) Calcium hydride is used as desiccant to remove moisture from organic solvents.
(iv) Hydride complexes are catalysts.
(v) Atomic hydrogen and oxy-hydrogen torches for cutting and welding.
(vl) Hydrogen is used in fuel cells for generating electrical energy.
(vii) Liquid hydrogen is used as a rocket fuel as well as in space research.
(viii) Metallic hydrides are used in battery applications.
