Elimination reaction often competes with substitution reactions. during this reaction, a substrate (typically an alkyl halide) eliminates one equivalent (unit) of acid to make an alkene. Two possible mechanisms are available for this chemical reaction . chemical reaction may be a sort of reaction is especially wont to transform saturated compounds (organic compounds which contain single carbon-carbon bonds) to unsaturated compounds (compounds which feature double or triple carbon-carbon bonds). An reaction may be a sort of a chemical reaction where several atoms either in pairs or groups are faraway from a molecule. The removal usually takes place thanks to the action of acids and bases or action of metals. It also can happen through the method of heating at high temperatures. Normally, elimination reactions are distinguished by the type of atoms or groups of atoms that leave the molecule. thanks to this, there are two main methods involved during this sort of reaction; within the dehydration method, there's the elimination of a water molecule mostly from compounds like alcohol. Sometimes, this method is additionally called Beta chemical reaction where the leaving group and H are placed at neighbour carbon atoms. On the opposite hand, in dehydrohalogenation, there's a removal of a atom and a halogen atom.
