Oxidation number of a compound must be 0.
Using the values for A, B and C in the four options we find that A3(BC4)2 is the answer.
Check : (+2)3 + [(+5)+4(–2)]2 = 6 + (5–8)2 = 0

Understanding Oxidation Numbers
In this compound, we have three elements: A, B, and C, with oxidation states of +2, +5, and -2, respectively. The goal is to find a formula that balances these oxidation numbers to achieve electrical neutrality.
Determining Total Oxidation States
1. Element A:
- Oxidation number = +2
- If we have 'x' atoms of A, the total contribution = +2x
2. Element B:
- Oxidation number = +5
- If we have 'y' atoms of B, the total contribution = +5y
3. Element C:
- Oxidation number = -2
- If we have 'z' atoms of C, the total contribution = -2z
Setting Up the Equation
For the compound to be neutral, the sum of oxidation states must equal zero:
+2x + 5y - 2z = 0
Analyzing Each Option
- Option a: A2(BC3)2
- Total contribution: 2(+2) + 2(+5) + 6(-2) = 4 + 10 - 12 = 2 (Not neutral)
- Option b: A3(BC4)2
- Total contribution: 3(+2) + 2(+5) + 8(-2) = 6 + 10 - 16 = 0 (Neutral)
- Option c: A3(B4C)2
- Total contribution: 3(+2) + 8(+5) + 2(-2) = 6 + 40 - 4 = 42 (Not neutral)
- Option d: ABC2
- Total contribution: 1(+2) + 1(+5) + 2(-2) = 2 + 5 - 4 = 3 (Not neutral)
Conclusion
The only formula that maintains electrical neutrality is option b: A3(BC4)2. This formula balances the oxidation states, confirming it as the correct answer.
