MCQ
Law of definite proportions does not apply to nitrogen oxide because
(a) Atomic weight of N is not constant
(b) Molecular weight of nitrogen is variable
(c) Atomic weight of oxygen is variable
(d) Nitrogen has different valencies in different oxides
Solution:
In different oxides of nitrogen, the valencies of nitrogen varies from +1 to +5. So, law of definite proportions does not apply to oxides of nitrogen.
Option (d) is correct.
