The degree of unsaturation, also known as the index of hydrogen deficiency or the double bond equivalent, is a measure used in organic chemistry to determine the number of pi bonds and rings present in a molecule. It is calculated from the molecular formula of the compound and is used to help draw the compound's structure.
