    Towards electrophilic reagents

    A)  ethene is more reactive than ethyne

    B)  ethene is less reactive than ethyne

    C)   both have equal reactivity

    D)  the reactivity of both cannot be predicted

    Correct Answer: A

    Solution :

                     Towards electrophilic reagents alkynes are less reactive than alkenes due to sp-hybridisation of carbon atoms and cylindrical nature of Ti-electron clouds. Hence, ethene is more reactive than ethyne towards electrophilic reagents.
