Answer to Question #141818 in Physical Chemistry for Suhani

Question

Which of the following pairs of comping illustrate law of multiple proportions

a. KOH, CsOH

b. H₂O, D₂O

c. Ethane, benzene

d. KCl, KBr

Answer 1

The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers.

Ethane and Benzene illustrate it as all other compounds are formed from different elements but Ethane(C₂H₆),Benzene(C₆H₆) are formed from same elements
