Which of the following compounds do not follow Law of definite proportion?
Which of the following compounds do not follow Law of definite proportion?
The correct options are
C Cr1.97 O3
D F0.95O
Laws of definite proportion states that chemical compound always contains exactly same amount of proportion by mass.
stoichiometric compounds are chemical compounds, having elemental composition whose proportions can be represented by integers.
For example FeO, for every one oxygen atom, there is one Fe atom, So the formula will be FeO.
This is a stoichiometric compound and it follows law of definite proportion.
But in nature Ferrous oxide contains the ratio of Fe and oxygen between 0.83 and 0.95 from sample to sample because of some imperfections in crystal. These compounds are non-stoichiometric compounds which doesn't follow law of definite proportion.
So Cr1.97O3 and Fe0.95O are non-stoichiometric compound given in the options.
