WebRecap - Cycloalkanes. The third homologous series is the cycloalkanes. Their names all end in –ane and begin with cyclo-, for example cyclopropane. The cycloalkanes have the general formula \ ( {C_n} {H_ {2n}}\). Even though they have the same general formula as the alkenes, the cycloalkanes are saturated and contain only single bonds. WebThe alkanes and alkenes react with oxygen. Their carbon atoms and hydrogen atoms gain oxygen. Addition reactions of alkenes. The functional group, C=C, allows alkenes to undergo addition reactions.

WebAll alkenes contain a double carbon bond, which is shown as two lines between two of the carbon atoms i.e. C=C All alkenes contain a double carbon bond, which is the functional group and is what allows alkenes to react in ways that alkanes cannot The names and structure of the first four alkenes are shown below: 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). rbt training activities
