Chemical Properties of Alkenes | Addition of Dihydrogen & Halogen

December 16, 2024 by Neeraj Anand, Param Anand
Alkenes consist of a large number of loosely held pi bonds. Due to the presence of such bonds they exhibit addition reactions. In addition reaction, the electrophiles (electron seeking species) are added to the double-bonded compounds which result in the formation of the additional product. Under special conditions, in some cases, it has the ability to undergo free radical substitution reactions also. Ozonolysis reaction and oxidation reaction are also prominently exhibited it.
