Q.Name the following.
A compound having hydrogen, aluminium and lithium as its constituent elements.

Lithium aluminium hydride, commonly abbreviated LAH, LiAlH4, is prepared by reacting lithium hydride with aluminium chloride, 4LiH + AlCl3 → LiAlH4 + 3LiCl. It is a colourless solid that reacts violently with water and even with atmospheric moisture, so it must always be handled under strictly anhydrous conditions, typically in dry ether. Because it readily supplies hydride ion (H⁻), LAH is one of the most useful reducing agents in organic synthesis: in dry ether it reduces an ester (R-CO-OR') to the corresponding alcohol (plus R'-OH), and it reduces a car …
