Types of Chemical Formulas

You may find several types of class 12 Chemistry formulas, but here are the four main types of chemical formulas you should know about:

• Molecular Formula: This formula is very simple; to show or write a molecular formula you just need to show the exact number and type of atoms in a molecule. To understand this better let’s take an example: the molecular formula of water is written like this, H2O. This indicates, there are two hydrogen atoms and one oxygen atom in this molecular formula.

• Empirical Formula: The empirical formula shows the simplest whole number ratio of the atoms in a molecule. Let's understand this better with an example. The Molecular formula of glucose is (C6H12O6), but we want to find out the Empirical formula, so let's simplify the ratio of 6:12:6 by dividing all those numbers with 6. The outcome of division by six will be this: 1:2:1. This ratio shows the simplest ratio of carbon to hydrogen to oxygen in glucose. Now, we can write the glucose formulas in Empirical formulas like this CH2O.

• Structural Formula: This formula helps you represent exactly how all the atoms are connected to each other with lines that represent bonds. To understand Structural formula let’s take an example of methane (CH₄). Here's how the structural formula for methane looks like — Carbon likes to make 4 bonds with other atoms. So, in methane, the carbon is in the middle, and each of the four hydrogen atoms is connected to it by a single bond.

• Condensed Formula: This formula simplifies the structural formula by showing the atoms and their bond in a more condensed form.
