    Study Notes

    Halogenation of Cycloalkanes and Cycloalkenes

    Products of Halogenation

    • Cycloalkanes undergo halogenation to form monohalogenated cycloalkanes.
    • Cycloalkenes undergo halogenation to form dihalogenated cycloalkenes.

    Reagents Used in Halogenation

    • Bromine liquid (Br2) is commonly used as a reagent in the halogenation of cycloalkanes and cycloalkenes.

    Role of Solvent in Halogenation

    • The solvent provides a medium for the reaction to occur.

    Confirmation of Halogenation Reaction

    • The success of the halogenation reaction can be confirmed by observing a change in color.

    Reactivity of Cycloalkanes and Cycloalkenes

    • Cycloalkenes are more reactive towards halogenation than cycloalkanes due to the presence of a double bond.

    Type of Reaction

    • Halogenation is a type of addition reaction.

    Effect of Double Bond on Reactivity

    • The presence of a double bond in cycloalkenes increases their reactivity towards halogenation compared to cycloalkanes.
