Vedclass · Answer

(C) Hydrogen has an oxidation state of $0$ in its elemental form $(H_2)$.It can lose electrons to form $H^+$ (oxidation state $+1$),acting as a reducing agent (e.g.,in the reduction of metal oxides).It can also gain electrons to form $H^-$ (oxidation state $-1$),acting as an oxidising agent (e.g.,in the formation of metal hydrides like $NaH$).Therefore,it can act as both an oxidising and a reducing agent.

List-$I$ (Type of hydride)	List-$II$ (Example)
$(A)$ Electron precise	$(i)$ $SiH_4$
$(B)$ Saline	$(ii)$ $H_2O$
$(C)$ Electron deficient	$(iii)$ $MgH_2$
$(D)$ Electron rich	$(iv)$ $B_2H_6$
