Insert the information in the form and the calculator will determine the degree of unsaturation.

What is the degree of unsaturation?

The degree of unsaturation is a calculation that counts the total number of rings and π bonds. It is used in the analysis of the molecular formula of organic molecules in order to help draw chemical structers.

How to calculate degree of unsaturation?

To calculate degree of unsaturation you should use the following formula:
degree of unsaturation = (2 (c) - H - x + N + 2) / 2
where:
c = number of carbon atoms
H = number of hydrogen atoms
x = number of halogen atoms
N = number of nitrogen atoms

example: Measure the degree of unsaturation for c5H4Ncl?

Using the degree of unsaturation formula the answer will be:
degree of unsaturation = (2 (c) - H - x + N + 2) / 2
degree of unsaturation = (2 (5) - 4 - 1 + 1 + 2) / 2
degree of unsaturation = 4

Why use degree of unsaturation?

The degree of unsaturation is used to probide information about the structure of the atom, for example it is used to indicate the total number of rings and pi bonds within a molecule which helps in finding out the molecular structure.
