The gaseous product $(s)$ expected at room temperature by reaction of sodium borohydride and boron trifluoride under anhydrous conditions is/are:
A
$H_2$
B
$B_2H_6$ and $H_2$
C
$B_2H_6$
D
$BH_2F$ and $H_2$
Solution
$3 \mathrm{Na}\left[\mathrm{BH}_{4}\right]+4 \mathrm{BF}_{3} \longrightarrow 2 \mathrm{B}_{2} \mathrm{H}_{6}(\mathrm{g})+3 \mathrm{Na}\left[\mathrm{BF}_{4}\right]$
$\mathrm{B}_{2} \mathrm{H}_{6}$ is the gaseous product
