An alkali metal hydride ( ( NaH ) ) reacts with diborane in ' ( A ) ' to give a tetrahedral compound 'ET which is extensively used as reducing agent in organic synthesis. The compounds 'A' and 'ET respectively are

Options

  1. A( C₂ H₆ ) and ( C₂ H₅ Na )
  2. B( CH ₃ COCH ₃ ) and ( B ₃ ~N ₃ H ₆ )
  3. C( C₆ H₆ ) and ( NaBH ₄ )
  4. D( (C₂ H₅ )₂ O ) and ( NaBH ₄ )

Correct answer

D. ( (C₂ H₅ )₂ O ) and ( NaBH ₄ )

Step-by-step solution

The reaction involved is 2 N a H+B₂ H₆^ (A) (C₂ H₅ )₂ O (B) 2 N a B H₄ The compound (B) is sodium borohydride ( ( NaBH ₄ ) ) which is a reducing agent in many organic syntheses.
