Question

A compound contains atoms of three elements A, B and C. If the oxidation number of A is + 2, B is +5 and that of C is - 2, the possible formula of the compound is (A) A2(BC3)2 (B) A3(BC4)2 (C) A3(B4C)2 (D) ABC2

Tardigrade Admin · Accepted Answer

In A3(BC4)2 3 x oxidation number of A + 2 [oxidation number of B + 4 x oxidation number of C ] = 0 3 x (+2) + 2 [5 + 4 x (-2)] = 0 6 + 2 [-31] = 0

Q. A compound contains atoms of three elements $A, B$ and $C$ . If the oxidation number of $A$ is $+ 2, B$ is $+ 5$ and that of $C$ is $- 2$ , the possible formula of the compound is

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

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

$A_{3} (B_{4} C)_{2}$

$A B C_{2}$

In $A_{3} (B C_{4})_{2} 3 x$ oxidation number of $A + 2$ [oxidation number of $B + 4 x$ oxidation number of $C$ ] = 0
$3 x (+ 2) + 2 [5 + 4 x (- 2)] = 0$
$6 + 2 [- 31] = 0$
