Alkenes can react with different types of chemicals during addition reactions. Alkene + hydrogen → alkane. This is called hydrogenation, and it needs a catalyst. For example:.

An alkene placed in an aqueous non-nucleophilic strong acid immediately "reaches out" with its double bond and attacks one of the acid's hydrogen atoms (meanwhile, the bond between oxygen and hydrogen performs heterolytic cleavage toward the oxygen—in other words, both electrons from the oxygen/hydrogen single bond move onto the oxygen atom)..

Ozonolysis of alkenes involves the addition of an ozone molecule (O 3) to alkene to form ozonide which are reduced with zinc dust and water to give smaller molecules. Cycloalkenes also undergo ozonolysis reaction. For example, cyclopropene on reductive ozonolysis gives propane-1,3-dial. Notice that in the above reaction only one product is formed.

Alkenes: Hydration (Direct Addition of Water) The addition of water to an alkene in the presence of a catalytic amount of strong acid leads to the formation of alcohols (hydroxy‐alkanes). This reaction proceeds via a standard carbocation mechanism and follows the Markovnikov rule. The mechanism for the addition of water to ethene follows. 1.

There are two possible scenarios for the starting alkene that we can have; 1) the starting material alkene has no chiral centers 2) there is a chiral center in the alkene. Let's start with the first option. Addition to an alkene with no stereogenic center For example, draw the major product (s) of the following reaction:.

Finally, if all the water reacted, it would give 6.94 mol H_{2}O × \left\lgroup\frac{2 mol H_{2}SO_{4} }{2 mol H_{2}O } \right\rgroup = 6.94 mol H_{2}SO_{4} In this case, SO_{2} is the limiting reactant because the computation based on its amount produces the smallest amount of product (6.24 mol H_{2}SO_{4} )..
