    No it cannot give semipinacole rearrangement. because F is different to remove

    but sir other halogens give this reaction na

    eduncle-logo-app

    yes, other halogen can be removed in presence of Ag+ and Hg2+

    eduncle-logo-app

    so why it can't

    eduncle-logo-app

    wait..

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    because R- F is more bond dissociation energy i.e, more amount of energy required to break bond between R and F

    eduncle-logo-app

    this is the reactivity order of RX

    eduncle-logo-app

    also you can correlate with leaving group ability. F is very poor leaving group so not easy to remove

    now got it??

    eduncle-logo-app

    yes sir

    eduncle-logo-app
