What is the order of reducing power of hydrides of alkali metals?also give reason for the order
The reducing character increases from sodium to Caesium.
The alkali metals show a +1 oxidation state. The alkali metals can easily lose their valence electron. Due to low ionization energy, the alkali metals can easily lose their valence electron act as good reducing agents and gain stable noble gas configuration.
But I asked about reducing power of hydrides of alkali metal
not of alkali metal
Will order be same?
The order of reactivity of the alkali metals towards hydrogen decreases as we move down the group from Li to Cs. Due to the reason that the lattice energies of these hydrides decreases progressively as the size of the metal cation increases and thus the stability of these hydrides decreases from LiH to CsH.
The statement that Reducing character of hydrides of alkali metal decreases down the group
It was a question from a test ...I could not show you as the app doesn't allow to take screenshot
as you said stability decreases down the group then MH should be easily dissociated and reducing character should increase
Correct me if I am wrong
