During the electrolysis of molten lithium hydride,hydrogen gas is liberated at the anode.

(C) In molten lithium hydride $(LiH)$,the compound dissociates into $Li^+$ and $H^-$ ions.During electrolysis,the $H^-$ ions migrate towards the anode (positive electrode).At the anode,the $H^-$ ions undergo oxidation to release hydrogen gas: $2H^- \rightarrow H_2(g) + 2e^-$.Therefore,hydrogen gas is liberated at the anode.
