The DBE formula is: DBE=C+1−H2−X2+N2DBE=C+1−2H−2X+2N where: DBEDBE— Double bond equivalent; CC— Number of carbon atoms; HH— Number of hydrogen atoms; XX— Number of halogen atoms; and NN— Number of nitrogen atoms. How to calculate the double bond equivalent Now that...
It has high reactivity and gives a network polymer having high crosslinking density by independently reacting the diacetylene group and the double bond. PREPARATION:A compound of formula I (R=R') can be produced e.g. by the oxidative coupling of a compound of formula II using a metal ...
Chemistry(GeneralAromaticity index (AI) and double-bond equivalent (DBE) were studied to seek a simpler approach in identifying suitable ionic liquids for the desulphurization process. Manifestation of interaction mechanism by COSMO-RS and Raman spectroscopy is discussed. The findings demonstrate that ...
Oxygen tends not to form triple bondsdue to formal charge reasons. If oxygen starts with 6 electrons and forms a triple bond, then it has 2 lone pair electrons. Using the formal charge formula, 6 - (2+6/2) = 1. Since oxygen is so electronegative, it'll tend not to have a positive...

We first calculated the shear stress component along the slip sense of the Mw 7.6 earthquake, then calculated the normal stress component, and finally used the Coulomb stress formula78 (Eq. 11) to calculate the regional stress changes at 10 km depth and on the rupture area of the Mw 7.6...
Alcohols having a double bond in the alpha position are conventionally converted into ketones in the presence of inorganic oxidizing agents (e.g. KMnO4, OsO4, H2SO4/H2CrO4). In particular, it is known to convert an alcohol of the formula (I) into a ketone of the formula (II) in this...

Given the Tax Foundation’s comprehensive formula, I don’t know what it will do to the overall tax rate on capital income, but it definitely will move in the wrong direction. Why is Trudeau pushing bad policy? Given that a previous class-warfare tax hike backfired, he should have learned...
a 2,5-disubstituted pyran ring as a constituent of the molecule; examples which may be mentioned are compounds which can be obtained by reaction of the exocyclic C═C double bond in the 5-position of the pyran ring of a compound of the formula I-C with suitable reactants (see below)...
