We can also calculate it using the formula. Double bond equivalent = C +1− 2H. . One degree of unsaturation is equivalent to 1 ring or 1 double bond (1 π bond). Two degrees of unsaturation is equivalent to 2 double bonds, 1 ring and 1 double bond, 2 rings, or 1 triple bond (2 π Importance: Double Bond Equivalents (DBE), is a measure of how unsaturated a molecule is. Physically, it is a measure of the number of {eq}H_2 {/eq} molecules that would have to be added to a A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compounds of dissolved organic matter (DOM).

D.B.E = (a+1)- { (b+e-c)/2} [D.B.E :- Double Bond Equivalence] For Ex. (1) D.B.E for CH4 is 0 hence no pi bond is present. Double bond equivalents (DBE) and hydrogen deficiency (Z) This page allows you to calculate the number of double bond equivalents (DBE), or rings plus double bonds, and the hydrogen deficiency, Z, for an organic molecule.

Rings plus Double Bonds Equivalent (RDBE) (also known as the degree/element of unsaturation or index of hydrogen deficiency) can be determined from a Molecular Formula (MF). The calculation provides insight into the number of rings and/or double bonds and/or triple bonds to expect from an unknown structure.
