DBE is defined as Double Bond Equivalent rarely. Correction for ‘Quantification of isomerically summed hydrocarbon contributions to crude oil by carbon number, double bond equivalent, and aromaticity using gas chromatography with tunable vacuum ultraviolet ionization’ by Jeremy A. Nowak et al., Analyst, 2018, 143, 1396–1405. DOUBLE BOND EQUIVALENT AND IT`S APPLICATION | Unacademy. NEET UG. Free classes & tests.

The DBE calculation tries to find the presence of unsaturation in a compound from the general molecular formula. The unsaturation is calculated in levels or degrees. 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.

A molecular formula of C 4 H 7 NO. A common model for the treatment of conjugated molecules is a composite valence bond / Hückel molecular orbital theory (VB/HMOT) treatment, in which the σ framework of the molecule is separated from the π system (or systems) of the molecule (see the article on the sigma-pi and equivalent-orbital models for this model and an alternative treatment). Double Bond Equivalent: DBE: Degenerate Band-Edge (photonic crystal) DBE: Data Bus Element: DBE: Double Below Elbow (amputation) DBE: Distorted-Wave Born Exchange: DBE: Departmental Budget Estimate: DBE: Dynamic Bias Estimator The Unsaturation Number (UN) Or Double‑Bond Equivalent (DBE) = 0. This problem has been solved! See the answer. Compound A has a molecular formula of C6H14O. #53 | Double Bond Equivalent video from NEET syllabus Chemistry - Organic Chemistry - Some Basic Principles And Techniques

Ring Double Bond Equivalents (RDBE) or Double Bond Equivalents (DBE) are calculated from valence values of elements contained in a formula and should tell the number of bonds - or rings. So, in the compound A, two cyclopentane rings are should be present along with a double bond. Due to the presence of two rings and one double bond in A its double bond equivalent is 3. We can also calculate it using the formula.

Ring Double Bond Equivalents (RDBE) or Double Bond Equivalents (DBE) are calculated from valence values of elements contained in a formula and should tell the number of bonds - or rings. The Double Bond Equivalence (DBE) can be defined as the total number of unsaturation's present in the organic molecule and unsaturation is nothing but consisting a double bond or a cyclic or ring system. For example Benzene the number of double bonds in benzene is 3 and it has 1 ring which means 4DBE. 1 like If the answer is not available please wait for a while and a community member will probably answer this soon. You can study other questions, MCQs, videos and tests for Chemistry on EduRev and even discuss your questions like Double bond equivalent in cubane is:Correct answer is '5'. Double bond equivalent (DBE; UN; degree of unsaturation; PBoR [Pi Bonds or Rings]): The number of molecules of H 2 that would have to be added to a molecule to convert all pi bonds to single bonds, and all rings to acyclic structures. Ring and double bond equivalent ; Deprecated: rings plus double bonds.
