question 57

Multiple Choice

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.
