MCQ

$BF_3$ on hydrolysis forms

A
$H_3BO_3$
B
$HBF_4$
✓
both $(A)$ and $(B)$
D
none of these

✓

Answer

Correct option: C.

both $(A)$ and $(B)$

c
$\mathrm{BF}_{3}$ Partial hydrolysis.

$\mathrm{BF}_{3}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{B}(\mathrm{OH})_{3}+3 \mathrm{HF}$

$3 \mathrm{HF}+3 \mathrm{BF}_{3} \rightarrow 3 \mathrm{H}\left[\mathrm{BF}_{4}\right]$

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

$4 \mathrm{BF}_{3}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{B}(\mathrm{OH})_{3}+3 \mathrm{H}\left[\mathrm{BF}_{4}\right]$
