A compound contains three elements `A,B` and `C`, if the oxidation number of `A=+2B=+5` and `C=-2` then possible formula of the compound is

A

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

B

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

C

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

D

`ABC_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Compound formed from A, B and C is that for which sum of oxidation number is zero.
`underset(+6)underset(uarr)(A_(3)) underset(+10)underset(uarr)B underset(-16)underset(uarr)((C_(4))_(2)) " correct"`
