Write any two examples of compounds which have same molecular and empirical formulae.
Part 1: Empirical formula of a compound:-
Part 2: Relation between molecular formula and empirical formula:-
Since,
Therefore,
If , the molecular formula and empirical formula are the same.
Part 3: Molecular and empirical formula of Formaldehyde (),:-
Compound | Molecular Formula | Whole Numbers | Simplest Ratio of Empirical Formula |
Formaldehyde |
Since , as a result, the molecular formula of formaldehyde () is the same as the empirical formula.
Part 4: Molecular and empirical formula of methane (),:-
Compound | Molecular Formula | Whole Numbers | Simplest Ratio of Empirical Formula |
Methane |
Since , as a result, the molecular formula of formaldehyde () is the same as the empirical formula.
Hence, two examples of compounds which have same molecular and empirical formulae are Formaldehyde()and Methane()
