MCQ
Diborane $(B_2H_6)$ reacts independently with $O_2$ and $H_2O$ to produce, respectively
- A$H_3BO_3$ and $B_2O_3$
- ✓$B_2O_3$ and $H_3BO_3$
- C$HBO_2$ and $H_3BO_3$
- D$B_2O_3$ and $[BH_4]^-$
✓
Answer
Correct option: B.
$B_2O_3$ and $H_3BO_3$
b
$B_2H_6 + 3H_2O \longrightarrow 2H_3BO_3 + 3H_2$
$B_2H_6 + 3H_2O \longrightarrow 2H_3BO_3 + 3H_2$
$B_2H_6 + 3O_2 \longrightarrow B_2O_3 + 3H_2O$
