What's C2H6O2 in empirical formula?

CH₃O

Explanation:

Data Given:

Molecular Formula = C₂H₆O₂

Empirical Formula = ?

Solution

Empirical Formula:

Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.

So,

tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule

C₂H₆O₂ Consist of Carbon (C), Hydrogen (H), and Oxygen (O)

Now

Look at the ratio of these three atoms in the compound

C : H : O

2 : 6 : 2

Divide the ratio by two to get simplest ratio

C : H : O

2/2 : 6/2 : 2/2

1 : 3 : 1

So for the empirical formula the simplest ratio of carbon to hydrogen to oxygen is 1:3:1

So the empirical formula will be

Empirical formula of C₂H₆O₂ = CH₃O
