Question

differentiate between non stoichiometric hydrides and saline hydrides. ​

Answer 1

Answer:

Non-Stoichiometric hydrides are hydrogen-deficient compounds formed by the reaction ofdihydrogen with d-block and f-block elements. These hydrides do not follow the law ofconstant composition. For example: LaH2.87, YbH2.55, TiH1.5 - 1.8 etc. Alkali metals formstoichiometric hydrides.

Saline hydrides (also known as ionic hydridesor pseudohalides) are compounds form between hydrogen and the most active metals, especially with the alkali and alkaline-earth metals of group one and two elements. In this group, the hydrogen acts as the hydride ion (H−). They bond with more electropositive metal atoms.
