Chemistry - Mole Concept Question with Solution | TestHub
Which of the following pair of compounds does not demonstrate the law of multiple proportion?
Options:
Answer:
Solution:
The law of multiple proportions states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in the ratio of small whole numbers.
This law is applicable only to pairs of compounds that are formed by the exact same two elements.
In the pair and , the compounds are composed of different sets of elements ( and ) and contain more than two elements. Therefore, they do not demonstrate the law of multiple proportions.
The other pairs ( and , and , and ) consist of the same two elements in different proportions, which illustrates the law of multiple proportions.
