Alkene Reactions

Iodination [I2] Iodination Definition: Iodination is a reaction where iodine is added to a double bond of alkene to give a diiodide. Iodination Explained: Alkene chlorination and bromination are very…

Hydrogenation of Alkenes Hydrogenation of Alkenes Definition: Catalytic hydrogenation involves the addition of molecular hydrogen (H2) across a double bond in the presence of a metal catalyst and the net result of…

Free Radical Addition of HBr Free Radical Addition of HBr Definition: When alkane is exposed to hydrogen bromide, alkyl bromide is formed. Free Radical Addition of HBr Explained: It was noticed that when freshly distilled…

Ether Formation [H+/ROH] Ether Formation [H+/ROH] Definition: An acid catalyzed hydro-alkoxy addition is the addition of an alcohol to carbon-carbon double bond to form an ether. Ether Formation Explained: When sulfuric acid is placed in…

Dihydroxylation [OsO4] Dihydroxylation Definition: When an alkene is treated with osmium tetroxide (OsO4), two hydroxyl groups are added to the alkene by cleaving the double bond. This process is called syn dihydroxylation. Dihydroxylation Explained: In this process,…

Dihydroxylation [KMnO4] Dihydroxylation Definition: When treated alkene with potassium permanganate, two hydroxyl groups are added, so the resulting compounds are called dihydroxylates of the reaction of syn-dihydroxylation. Dihydroxylation Explained: In basic conditions, the diol is formed by treating alkene…

Dichlorocyclopropanation Dichloropropanation Definition: Dichloropropanation is a type of cyclopropanation in which two atoms of hydrogen from methylene are replaced by chlorine atoms. Cyclopropanation refers to any chemical process that generated…

Cyclopropanation Cyclopropanation Definition: Cyclopropanation refers to any chemical process which generates cyclopropane rings. Cyclopropanation Explained: Cyclopropanes may be quite readily prepared by the addition of reactive species called carbenes to the double bond of alkenes. In…
