The reaction of H3N3B3Cl3{H}_{3}{N}_{3}{B}_{3}C{l}_{3}\left(A\right)withLiBH4inwith LiB{H}_{4} intetrahydrofuran gives inorganic benzene \left(B\right) . Further, the reaction of \left(A\right) with \left(C\right) leads toH3N3B3(Me){H}_{3}{N}_{3}{B}_{3}{\left(Me\right)}_{3}.Compounds(B). Compounds \left(B\right) and \left(C\right) respectively, are:

Options

  1. ABogging god MeBrMeBr
  2. BDiborane and MeMgBrMeMgBr
  3. CBoron nitride and MeBrMeBr
  4. DBorazine and MeMgBrMeMgBr

Correct answer

D. Borazine and MeMgBrMeMgBr

Step-by-step solution

The reaction of H3N3B3Cl3{H}_{3}{N}_{3}{B}_{3}C{l}_{3}\left(A\right)withLiBH4inwith LiB{H}_{4} intetrahydrofuran gives inorganic benzene \left(B\right). The reaction is given below.
