Which of the following is an empirical formula? H6O2 H402 H2O H2O2
2 answers:
- Empirical formula represents a molecule with its elements combined in simplest ratio, it's not necessarily same as the form in which the compound really exists in the nature. Hence we can say that empirical formula shows the simple ratios in which atoms combined to form a molecule.
For example : Hydrogen peroxide
- Hydrogen peroxide exists in nature as , which is its molecular formula.
but it's empirical formula will be H0 [ simplest ratio of 1 : 1 ]
Therefore, the correct choice is :
- C.
