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

    A)  \[C{{H}_{3}}COC{{H}_{3}}\]and \[{{B}_{3}}{{N}_{3}}{{H}_{6}}\]

    B)  \[{{({{C}_{2}}{{H}_{5}})}_{2}}O\] and \[NaB{{H}_{4}}\]

    C)  \[{{C}_{2}}{{H}_{6}}\]and \[{{C}_{2}}{{H}_{5}}Na\]

    D)  \[{{C}_{6}}{{H}_{6}}\]and \[NaB{{H}_{4}}\]

    Correct Answer: B

    Solution :

    : \[2NaH+{{B}_{2}}{{H}_{6}}\xrightarrow[A]{{{({{C}_{2}}{{H}_{5}})}_{2}}O}\underset{B}{\mathop{\underset{Sodium\,borohydride}{\mathop{2NaB{{H}_{4}}}}\,}}\,\]
