    Study Notes

    Alkene Nomenclature

    • When naming alkenes, the carbons in a chain are numbered starting from the end that is closer to the double bond.

    Alternative Term for Alkenes

    • Another term for an alkene is an olefin.

    Isomerism in Alkenes

    • Alkenes exhibit geometric isomerism (also known as cis-trans isomerism).

    Hybridization in Double Bonds

    • Carbon atoms in a double bond exhibit sp² hybridization.

    Naming Cyclic Alkenes

    • The prefix "cyclo" is used when naming cyclic alkenes.

    Preferred Term for Hydrocarbons with C-C Double Bond

    • The preferred term for a hydrocarbon containing a C-C double bond is an alkene.
