Question

Among the following pairs of compounds, the one that illustrates the law of multiple proportions is (A) NH3 and NCl3 (B) H2S and SO2 (C) CuO and Cu2O (D) CS2 and FeSO4

According to the concept of law of multiple proportions, if two elements chemically combine to give two or more compounds, then the weight of one element which combines with the fixed weight of the other element in those compound, bear simple multiple ratios to one another.
Hence,

C u O

and

C u_{2} O

form two different compounds in a ratio of

1 : 2

with the fixed weight of oxygen.
