A compound contains atoms X, Y and Z. The oxidation number of X is `+3`, Y is `+5` and Z is `-2`. The possible formula of the compound isA. `XYZ_(2)`B. `Y_(2)(XZ_(3))_(2)`C. `X_(3)(YZ_(4))_(3)`D. `X_(3)(Y_(4)Z)_(2)`

Answer» Correct Answer - C
Let formula is `X_(x),Y_(y),Z_(z)`. O.N of X, Y and Z are `+3, +5 and -2` respecitvely
`:. 3x +5y - 2z=0`. The values of x,y and z satisfying this equation are 3,3 and 12 Therefore correct formula is `X_(3)(YZ_(4))_(3)`.
