Vedclass · Answer

(B) In $MH_2$,$M$ represents an alkaline earth metal (Group $2$ element). Since the metal $M$ is in its $+2$ oxidation state,the sum of oxidation numbers must be zero. Let the oxidation number of $H$ be $x$. $1 	imes (+2) + 2 	imes (x) = 0$ $2 + 2x = 0$ $2x = -2$ $x = -1$. Therefore,hydrogen in metal hydrides like $MH_2$ exhibits a $-1$ oxidation state.
