Question

What is the second member of the alkene series?

Answer 1

Alkene

• “Alkenes are unsaturated hydrocarbons containing at least one double bond”.

Homologous series

• Homologous series refers to a set of organic compounds that have similar structural properties but differ from adjacent members by the $-{\mathrm{CH}}_2$ group. They have the same general formula and share the same functional group; therefore, their chemical characteristics are similar, but their physical properties differ due to differences in mass
• The general formula for the homologous series of alkenes is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n}}$ where n is the number of carbon atom.
• The first four-member of the alkene series is ethene, propene, butene, and pentene.

Second member of alkene series

• The second member of the alkene series is propene.
• Propene is represented as ${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2$.
