Which of the following can't explain law of reciprocal proportions?

1) H2O, CH4, CO 2) H2S, SO2, H2O 3) HF, CF4, CH4, 4) N2O, NO2, N2O4

Answer 2

Answer:

N₂O, NO₂, N₂O₄ can't explain the law of reciprocal proportions.

Explanation:

The law of reciprocal proportions states that when 2 elements combine separately, each with a fixed mass of a given third element, the ratio of the masses in which they do so are either equal, or can be expressed as a simple multiple of the ratio of their masses they combine with each other.

So, the pre-requisite of this law is 3 elements - 1 volume each of the former 2, and 2 equal volumes of the latter 1.

However, in the given question, the set of products N₂O, NO₂, N₂O₄ can’t define the given law, since they are different products of the same reactant elements.
