WebOzonolysis 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. … WebThis is a type of a reduction reaction where you use hydrogen gas at a reasonably high pressure to get rid of the double bond. This reaction of alkenes happens on the surface of a metal catalyst. The typical catalysts for the alkene hydrogenation are the platinum (Pt), palladium (Pd), and nickel (Ni).

WebAddition reactions. Alkenes are more reactive than alkanes and cycloalkanes because they have a double bond. In an addition reaction, the double bond of the alkene partially breaks when the reactant molecule attacks and adds on across it. Example. Addition of bromine water can be used as a test for unsaturation. WebReactions of alkenes Q6: What is the functional group of an alkene?

WebDec 1, 2015 · In alkenes, the high electron density of the carbon–carbon double bond leads to attack on these molecules by electrophiles. This section also covers the mechanism of addition to the double bond and introduces addition polymers, which are commercially important and have many uses in modern society. Structure, bonding and reactivity WebThe double C=C bond is what makes alkenes reactive. It can break open and new atoms can be added across it. Alkenes are not always small molecules. How do you test for an alkene? Alkenes turn bromine water from orange to colourless. Universal indicator turns purple in the presence of an alkali.
