Which of the following compounds have the same empirical formula?
The empirical formula of a compound represents the simplest whole number ratio of atoms present in the compound. It is an essential piece of information in chemistry as it helps us understand the composition of a substance. In this article, we will explore various compounds and determine which among them share the same empirical formula.
Firstly, let’s consider water (H2O) and hydrogen peroxide (H2O2). Both compounds contain hydrogen and oxygen, but in different ratios. The empirical formula of water is H2O, while that of hydrogen peroxide is H2O2. Therefore, these two compounds do not have the same empirical formula.
Moving on to carbon dioxide (CO2) and carbon monoxide (CO), both contain carbon and oxygen. However, the empirical formula of carbon dioxide is CO2, and that of carbon monoxide is CO. Hence, they do not have the same empirical formula.
Now, let’s examine glucose (C6H12O6) and fructose (C6H12O6). Both compounds contain carbon, hydrogen, and oxygen, and their empirical formulas are the same: C6H12O6. This means that glucose and fructose have the same empirical formula.
Next, we have methane (CH4) and ethane (C2H6). Both compounds contain carbon and hydrogen, but their empirical formulas differ. The empirical formula of methane is CH4, while that of ethane is CH3. Therefore, methane and ethane do not have the same empirical formula.
Lastly, let’s compare sodium chloride (NaCl) and potassium chloride (KCl). Both compounds contain sodium or potassium and chlorine, but their empirical formulas are different. The empirical formula of sodium chloride is NaCl, and that of potassium chloride is KCl. Hence, sodium chloride and potassium chloride do not have the same empirical formula.
In conclusion, glucose and fructose are the only compounds among the ones discussed that have the same empirical formula. Understanding the empirical formula of compounds is crucial in chemistry as it provides insights into their composition and properties.
