Vedclass · Answer

(A) The oxidation state of hydrogen is $-1$ in metal hydrides (where hydrogen is bonded to a less electronegative element) and $+1$ in compounds where hydrogen is bonded to a more electronegative non-metal.In $LiAlH_4$, hydrogen is present as a hydride ion $(H^-)$, so its oxidation state is $-1$.In $H_2O$, hydrogen is bonded to oxygen (which is more electronegative), so its oxidation state is $+1$.Therefore, $X = LiAlH_4$ and $Y = H_2O$.

Oxidation state of hydrogen in compound $X$ is $-1$ and in compound $Y$ is $+1$. $X$ and $Y$ are respectively
