Both LiAlH₄ and NaBH₄ are reducing agents.Which statement about these reagents is true? A)Both reagents contain polar metal-hydrogen bonds.The polarity of the B-H bond is greater than the polarity of the Al-H bond,so LiAlH₄ is the stronger reducing agent. B)Both reagents contain polar metal-hydrogen bonds.The polarity of the B-H bond is greater than the polarity of the Al-H bond,so LiAlH₄ is the weaker reducing agent. C)Both reagents contain polar metal-hydrogen bonds.The polarity of the B-H bond is less than the polarity of the Al-H bond,so LiAlH₄ is the stronger reducing agent. D)Both reagents contain polar metal-hydrogen bonds.The polarity of the B-H bond is less than the polarity of the Al-H bond,so LiAlH₄ is the weaker reducing agent.

Both LiAlH₄ and NaBH₄ contain polar metal-hydrogen bonds, but the Al-H bond in LiAlH₄ is more polar than the B-H bond in NaBH₄. This means that LiAlH₄ is the stronger reducing agent. Therefore, the correct statement is that the polarity of the B-H bond is less than the polarity of the Al-H bond, and LiAlH₄ is the stronger reducing agent.
