WebAug 25, 2024 · Alkenes react because the electrons in the p i bond attract things with any degree of positive charge. Anything which increases the electron density around the double bond will help this. Alkyl groups have a tendency to "push" electrons away from themselves towards the double bond. 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.
