Question

Illustrate how CH4 and C2H6 follow law of multiple proportions​

Answer 1

Explanation:

Law of definite composition: The elements which are present in the compound is combined in the same proportion by mass.

Law of multiple proportions: When two or more compounds are formed by the combination of two elements then the mass ratio of one element is combined with the fixed mass of the other element.

The case of methane, which consists of one carbon atom and four hydrogen atoms implies that has definite composition. In terms of mass, in methane, carbon and hydrogen atoms are combined in a definite ratio i.e. 12 g C/ 4 g H. Thus, methane has definite composition.

Now, carbon and hydrogen combine to give a class i.e. hydrocarbon. In this case, for every constant mass of carbon the ratio of hydrogen will always reduce to a 4/3 ratio for the formation of ethane (hydrocarbon). Thus, the law of multiple proportions followed.

Similarly, insso consists of exact atoms but in different ratios.

there fore heof ethane, which consists of two carbon atoms and six hydrogen atoms implies that has definite composition. In terms of mass, in ethane, carbon and hydrogen atoms are combined in a definite ratio i.e. 24 g C/ 6 g H. Thus, methane has definite composition.

Now, carbon and hydrogen combine to give a class i.e. hydrocarbon. In this case, for every constant mass of carbon the ratio of hydrogen will always reduce to a specific ratio for the formation of methane (hydrocarbon). Thus, the law of multiple proportions followed.
