The given molecular formula of the compound is {eq}{C_9}{H_{10}} {/eq}. The number of double bond equivalent can be calculated as follows; {eq}\begin{align*} DBE = C
The double bond is also stronger, 636 kJ mol −1 versus 368 kJ mol −1 but not twice as much as the pi-bond is weaker than the sigma bond due to less effective pi-overlap. In an alternative representation, the double bond results from two overlapping sp 3 orbitals as in a bent bond . One degree of unsaturation is equivalent to 1 ring or 1 double bond (1 [latex] \pi [/latex] bond). Two degrees of unsaturation is equivalent to 2 double bonds, 1 ring and 1 double bond, 2 rings, or 1 triple bond (2 [latex] \pi [/latex] bonds). A double-barreled bond is a municipal bond in which the interest and principal payments are pledged by two distinct entities—revenue from a defined project and the issuer and its taxing power. 8.

IUPAC RECOMMENDATIONS 2013: Ring and double bond equivalent ; Deprecated: rings plus double bonds.. Conventional measure of the degree of unsaturation of an organic molecule given by X - Y/2 + Z/2 + 1 where X is the number of carbon atoms, Y is the number of hydrogen or halogen atoms and Z is the number of nitrogen and phosphorus atoms.
DBE stands for Double Bond Equivalent. DBE is defined as Double Bond Equivalent rarely.
implies no double bonds, no rings. implies either 1 double bond or 1 ring implies either 2 double bonds, 2 rings or 1 double bond and 1 ring. and so on. So this formula isn't too useful unless you have extra information that would allow you to eliminate the chance of rings - meaning that the number will be just the number of double bonds.
In the analysis of the molecular formula of organic molecules, the degree of unsaturation (also known as the index of hydrogen deficiency (IHD), double bond equivalents, or unsaturation index) is a calculation that determines the total number of rings and π bonds. A formula is used in organic chemistry to help draw chemical structures.
