Question

B can be obtained from halide by van Arkel method. This involves reaction

$2 {BCl}_{3} + 3 H_{2} \overset{red hot W or Ta}{\to} 2 B + 6 HCl$
$2 {BI}_{3} \overset{red hot W or Ta}{\to} 2 B + 3 I_{2}$
Both (a) and (b)
None of the above

The correct answer is: $2 BI subscript 3 rightwards arrow with text red hot end text straight W text or end text Ta on top 2 straight B plus 3 straight I subscript 2$
