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

B

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

C

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

D

`ABC_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Sum of oxidation numbers of all atoms in a neutral molecule is zero.
`to A_(3)(B_(4)C):2xx3+2xx[4xx5-2]=42ne0`
`to A_(3)(BC_(4))_(2):+2xx3+2xx[+5-8]=0`
`to A_(2)(BC_(3))_(2):+2xx2+2xx[+5-6]=+2 ne0`
`to ABC_(2):+2+5+(-2)xx2=+3 ne0`
