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

A

`A_2(BC_3)_2`

B

`A_3(BC_4)_2`

C

`A_3(B_4_2`

D

`ABC_2`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Oxidation number of a compound must be 0. Using the values for A, B and C in the four options, we find that `A_3(BC_4)_2`, is the answer. Check: (+2)3 + [(+5)+4(-2)]2=6+(5-8)2 =0
