Q30 / 90 · KVPY 2011 (SB/SX) · Chemistry
All the products formed in the oxidation of $\mathrm{NaBH}_{4}$ by $\mathrm{I}_{2}$, are
- A$\mathrm{B}_{2} \mathrm{H}_{6}$ and $\mathrm{NaI}$
- Correct answerB$\mathrm{B}_{2} \mathrm{H}_{6}, \mathrm{H}_{2}$ and $\mathrm{NaI}$
- C$\mathrm{BI}_{3}$ and $\mathrm{NaH}$
- D$\mathrm{NaBI}_{4}$ and $\mathrm{HI}$
Solution
$\mathrm{Na} \mathrm{BH}_{4}+\mathrm{I}_{2} \rightarrow \mathrm{Nal}+\mathrm{B}_{2} \mathrm{H}_{6}+\mathrm{H}_{2}$
Hence, the correct answer is option: 'B'.
