Given below are the statements about diborane. \((a)\) Diborane is prepared by the oxidation of \(\mathrm{NaBH}_{4}\) with \(\mathrm{I}_{2}\). \((b)\) Each boron atom is in sp \(^{2}\) hybridized state. \((c)\) Diborane has one bridged \(3\) centre\(-2-\)electron bond. \((d)\) Diborane is a planar molecule. The option with correct statement(s) is :
- A \((c)\) and \((d)\) only
- B \((c)\) only
- C \((a)\) only
- D \((a)\) and \((b)\) only
Answer & Solution
Correct Answer
(C) \((a)\) only
Step-by-step Solution
Detailed explanation
Diborane is prepared by the reaction of \(\mathrm{NaBH}_{4}\) with \(\mathrm{I}_{2}\). \(2 \mathrm{NaBH}_{4}+\mathrm{I}_{2} \rightarrow \mathrm{B}_{2} \mathrm{H}_{6}+2 \mathrm{NaI}+\mathrm{H}_{2}\) In diborane, ' \(B^{\prime}\) is \(\mathrm{sp}^{3}\) hybrid, it is Non-planar and…
