Q. A compound contains X, Y and Z atoms. The oxidation states of X, Y and Z are +2, +2 and -2 respectively. The possible formula of the compound is
A) $XYZ_{2}$
B) $Y_{2}\left( XZ_{3} \right)_{2}$
C) $X_{3}\left( Y_{4}Z \right)_{2}$
D) $X_{3}\left( YZ_{4} \right)_{3}$
Explanation
(a)
Valencies of X, Y and Z is +2, +2 and -2 respectively so, they will form a compound having of formula $XYZ_{2}.$
