Oxidative addition is a process by which an atom is simultaneously oxidized and the number of bonds to it is increased as groups are added. The term oxad is used to denote this type of reaction. This type of process is not limited to coordination compounds, and it is easy to find numero...
Video on addition of HX to alkenes Problem EA1.1. The reaction of 2-methylpropene (or isobutylene) with HBr, as depicted above, is really a 2-step process. Draw this mechanism again and in each of the two steps label both the nucleophile and the electrophile (so, that’s four labels)...

For the first time, resolution is good enough to assignionization energies to the inequivalent carbons in propene and2-methylpropene. A linear correlation is found between the ionizationenergies and activation energies for addition of the electrophiles HF,HCl, HBr and HI to these molecules. The ...
The radiation-induced addition of HBr to alpha-olefins from propene to octene has been investigated from 79 to + 25掳C. The addition is predominately abnormal, or anti-Markownikoff, giving rise to the primary bromide which is well over 90 per cent of the product in most cases. The ...
