Which of the following chemical reactions and properties correctly describe the behavior of hydrides — Hydrogen Chemistry Question

💡 Solution & Explanation

$LiH$ reacts with $AlCl_3$ and $B_2H_6$ to synthesize complex hydrides $LiAlH_4$ and $LiBH_4$, respectively. $CaH_2$ (Hydrolith) reacts violently with water to liberate $H_2$. Complex metal hydrides are highly powerful *reducing* agents, not oxidizing agents.
