1,1-Dibromoethane is a clear, slightly brown, flammable chemical compound. [3] It is classified as the organobromine compound, and has the chemical formula C 2 H 4 Br 2 [4] and it is a position isomer of 1,2-dibromoethane. It is commonly seen in industrial chemistry, where it is used as a fuel additive. [5]
Double bond equivalent, a calculation used in chemistry that determines the total number of rings and π bonds of organic molecules DBE (drug) , also known as estrobin, a synthetic estrogen Dibromoethane , referring to either 1,1-Dibromoethane or 1,2-Dibromoethane, both being isomeric organobromides of each other
Dibromoethane can refer to either of two isomeric organobromides with the molecular formula C 2 H 4 Br 2: 1,1-Dibromoethane (ethylidene dibromide) 1,2-Dibromoethane (ethylene dibromide)
1,2-Dibromoethane has wider applications in the preparation of other organic compounds including those carrying modified diazocine rings [9] and vinyl bromide that is a precursor to some fire retardants. [4] In organic synthesis, 1,2-dibromoethane is used to brominate carbanions and to activate magnesium for certain Grignard reagents.
The molecular formula C 2 H 4 Br 2 (molar mass: 187.86 g/mol, exact mass: 185.8680 u) may refer to: 1,1-Dibromoethane (ethylidene dibromide) 1,2-Dibromoethane , or ethylene dibromide (EDB)
For hydrocarbons, the DBE (or IHD) tells us the number of rings and/or extra bonds in a non-saturated structure, which equals the number of hydrogen pairs that are required to make the structure saturated, simply because joining two elements to form a ring or adding one extra bond (e.g., a single bond changed to a double bond) in a structure reduces the need for two H's.
The preparation of EtBr stands as a model for the synthesis of bromoalkanes in general. It is usually prepared by the addition of hydrogen bromide to ethene: . H 2 C=CH 2 + HBr → H 3 C-CH 2 Br
In chemistry, the law of multiple proportions states that in compounds which contain two particular chemical elements, the amount of Element A per measure of Element B will differ across these compounds by ratios of small whole numbers. For instance, the ratio of the hydrogen content in methane (CH 4) and ethane (C 2 H 6) per measure of carbon ...
