MCQ
In the reaction ${B_2}{O_3} + C + C{l_2} \to A + CO.$ The $A$ is
  • ✓
    $BC{l_3}$
  • B
    $BC{l_2}$
  • C
    ${B_2}C{l_2}$
  • D
    $CC{l_2}$
✓

Answer

Correct option: A.
$BC{l_3}$
a
(a) ${B_2}{O_3} + 3C + 3C{l_2} \to 2BC{l_3} + 3CO$

$BC{l_3}$ is obtained by passing chlorine over the heated mixture of ${B_2}{O_3}$ and powdered charcoal.
