A3(BC4)2 3 (+ 2) + 2[ 1 (+ 5) + 4 (- 2)] = 6 + 2 (- 3) = 0 As the molecule is neutral, the sum of oxidation numbers must be zero

Q. $A, B$ and $C$ are three elements forming a part of compound in oxidation states of $+ 2, + 5$ and $- 2$ respectively. What could be the compound if molecule is neutral?

$A_{2} (BC)_{2}$

$A_{2} (B C_{4})_{3}$

$A_{3} (B C_{4})_{2}$

$A BC$

$A_{3} (B C_{4})_{2}$
$3 (+ 2) + 2 [1 (+ 5) + 4 (- 2)] = 6 + 2 (- 3) = 0$
