Identify the correct statements:
i. Oxidation of \(\mathrm{NaBH}_4\) with \(\mathrm{I}_2\) gives \(\mathrm{B}_2 \mathrm{H}_6\)
ii. \(\mathrm{B}_2 \mathrm{H}_6\) burns in oxygen and releases an enormous amount of energy
iii. \(\mathrm{B}_2 \mathrm{H}_6\) on hydrolysis gives a tribasic acid
- A i, ii, iii
- B i, ii only
- C i, iii only
- D ii, iii only
Answer & Solution
Correct Answer
(B) i, ii only
Step-by-step Solution
Detailed explanation
(i) \(2 \mathrm{NaBH}_4+\mathrm{I}_2 \rightarrow \mathrm{~B}_2 \mathrm{H}_6+2 \mathrm{NaI}+\mathrm{H}_2\) (ii) \(\mathrm{B}_2 \mathrm{H}_6+3 \mathrm{O}_2 \rightarrow \mathrm{~B}_2 \mathrm{O}_3+3 \mathrm{H}_2 \mathrm{O}+\) Energy (iii)…
