A compound contains atom A, B and C . The oxidation number of A is +2, of B is +5 and C is -2. The possible formula of the compound is

A

`A_(3)(BC_(4))_(2)`

B

`A_(3)(B_(4)C)_(2)`

C

`ABC_(2)`

D

`A_(3)(BC_(3))_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Sum of oxidation number of all the elements in the molecular formula of any compound is zero. Putting the O.N of all the elements in the molecular formula of the compounds, we find that in `A_(3)(BC_(4))_(2)`, the sum of O.N. of all the elements is ,
`3 xx (+2) + 2 xx [5 + 4(-2)]=0`.
