Instantly determine the Degree of Unsaturation (DU), also known as the Index of Hydrogen Deficiency (IHD), for any organic compound. This essential tool helps predict the number of rings and pi bonds in a molecule directly from its chemical formula, aiding in structural elucidation for organic chemistry students and professionals alike.
Formula:
The Degree of Unsaturation (DU) is calculated using the following formula:
DU = 1 + (C - H/2 - X/2 + N/2)
Where:- C = Number of Carbon atoms
- H = Number of Hydrogen atoms
- X = Number of Halogen atoms (Fluorine, Chlorine, Bromine, Iodine)
- N = Number of Nitrogen atoms
- Oxygen and Sulfur atoms do not affect the Degree of Unsaturation.
