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). WebEthene follows this pattern. Pentane does not follow this pattern and is an alkane. Why are alkenes more reactive than alkanes? The double C=C bond is what makes alkenes …

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. 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. bit missing crossword clue
