      Addition Reactions: Summary . Alkenes contain the unsaturated C=C functional group which characteristically undergo addition reactions. This is driven by the conversion of the weaker π bond into 2 new, stronger σ bonds. The reactions of alkenes can seem a little bewildering as a wide variety of reagents undergo this type of reaction providing ...

      Addition polymers are formed from alkenes. Alkenes can be made to join together in the presence of high pressure and a suitable catalyst. The π-bond breaks and the molecules join together. No other product is formed, and so this is known as . addition polymerisation. Since the polymers are made from alkenes they are also known as . polyalkenes.

      Addition reactions of alkynes are also named from the reagent used to cause the addition/convert the triple - C = C- to single C- C bond. (i)Hydrogenation Hydrogenation is an addition reaction in which hydrogen in presence of Palladium/Nickel catalyst at 150oC temperatures react with alkynes to form alkenes then alkanes.

      Aromatic compounds do not undergo addition reactions, because they would lose this special stability. Alkenes, however, are much more reactive than the other two classes. They have electron-rich double bonds (their pi electrons are not completely delocalized, even in conjugated alkenes) that allow them to easily undergo addition reactions.
